Bump version: 0.22.0 → 0.22.1-beta.0

add the tag related API to list existing tags, attach tag to a version,
update the tag version, delete tag, get the version of the tag, and
checkout the version that the tag bounded to.

<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->
## Summary by CodeRabbit

- **New Features**
- Introduced table version tagging, allowing users to create, update,
delete, and list human-readable tags for specific table versions.
  - Enabled checking out a table by either version number or tag name.
- Added new interfaces for tag management in both Python and Node.js
APIs, supporting synchronous and asynchronous workflows.

- **Bug Fixes**
  - None.

- **Documentation**
- Updated documentation to describe the new tagging features, including
usage examples.

- **Tests**
- Added comprehensive tests for tag creation, updating, deletion,
listing, and version checkout by tag in both Python and Node.js
environments.

+# Late interaction & MultiVector embedding type
+Late interaction is a technique used in retrieval that calculates the relevance of a query to a document by comparing their multi-vector representations. The key difference between late interaction and other popular methods:
+
+![late interaction vs other methods](https://raw.githubusercontent.com/lancedb/assets/b035a0ceb2c237734e0d393054c146d289792339/docs/assets/integration/colbert-blog-interaction.svg)
+
+
+[ Illustration from https://jina.ai/news/what-is-colbert-and-late-interaction-and-why-they-matter-in-search/]
+
+<b>No interaction:</b> Refers to independently embedding the query and document, that are compared to calcualte similarity without any interaction between them. This is typically used in vector search operations.
+
+<b>Partial interaction</b> Refers to a specific approach where the similarity computation happens primarily between query vectors and document vectors, without extensive interaction between individual components of each. An example of this is dual-encoder models like BERT.
+
+<b>Early full interaction</b> Refers to techniques like cross-encoders that process query and docs in pairs with full interaction across various stages of encoding. This is a powerful, but relatively slower technique. Because it requires processing query and docs in pairs, doc embeddings can't be pre-computed for fast retrieval. This is why cross encoders are typically used as reranking models combined with vector search. Learn more about [LanceDB Reranking support](https://lancedb.github.io/lancedb/reranking/).
+
+<b>Late interaction</b> Late interaction is a technique that calculates the doc and query similarity independently and then the interaction or evaluation happens during the retrieval process. This is typically used in retrieval models like ColBERT. Unlike early interaction, It allows speeding up the retrieval process without compromising the depth of semantic analysis.
+
+## Internals of ColBERT 
+Let's take a look at the steps involved in performing late interaction based retrieval using ColBERT:
+
+• ColBERT employs BERT-based encoders for both queries `(fQ)` and documents `(fD)`
+• A single BERT model is shared between query and document encoders and special tokens distinguish input types: `[Q]` for queries and `[D]` for documents
+
+**Query Encoder (fQ):**
+• Query q is tokenized into WordPiece tokens: `q1, q2, ..., ql`. `[Q]` token is prepended right after BERT's `[CLS]` token
+• If query length < Nq, it's padded with [MASK] tokens up to Nq.
+• The padded sequence goes through BERT's transformer architecture
+• Final embeddings are L2-normalized.
+
+**Document Encoder (fD):**
+• Document d is tokenized into tokens `d1, d2, ..., dm`. `[D]` token is prepended after `[CLS]` token
+• Unlike queries, documents are NOT padded with `[MASK]` tokens
+• Document tokens are processed through BERT and the same linear layer
+
+**Late Interaction:**
+• Late interaction estimates relevance score `S(q,d)` using embedding `Eq` and `Ed`. Late interaction happens after independent encoding
+• For each query embedding, maximum similarity is computed against all document embeddings
+• The similarity measure can be cosine similarity or squared L2 distance
+
+**MaxSim Calculation:**
+```
+S(q,d) := Σ max(Eqi⋅EdjT)
+          i∈|Eq| j∈|Ed|
+```
+• This finds the best matching document embedding for each query embedding
+• Captures relevance based on strongest local matches between contextual embeddings
+
+## LanceDB MultiVector type
+LanceDB supports multivector type, this is useful when you have multiple vectors for a single item (e.g. with ColBert and ColPali).
+
+You can index on a column with multivector type and search on it, the query can be single vector or multiple vectors. For now, only cosine metric is supported for multivector search. The vector value type can be float16, float32 or float64. LanceDB integrateds [ConteXtualized Token Retriever(XTR)](https://arxiv.org/abs/2304.01982), which introduces a simple, yet novel, objective function that encourages the model to retrieve the most important document tokens first. 
+
+```python
+import lancedb
+import numpy as np
+import pyarrow as pa
+
+db = lancedb.connect("data/multivector_demo")
+schema = pa.schema(
+    [
+        pa.field("id", pa.int64()),
+        # float16, float32, and float64 are supported
+        pa.field("vector", pa.list_(pa.list_(pa.float32(), 256))),
+    ]
+)
+data = [
+    {
+        "id": i,
+        "vector": np.random.random(size=(2, 256)).tolist(),
+    }
+    for i in range(1024)
+]
+tbl = db.create_table("my_table", data=data, schema=schema)
+
+# only cosine similarity is supported for multi-vectors
+tbl.create_index(metric="cosine")
+
+# query with single vector
+query = np.random.random(256).astype(np.float16)
+tbl.search(query).to_arrow()
+
+# query with multiple vectors
+query = np.random.random(size=(2, 256))

+
+### distanceType?
+
+```ts
+optional distanceType: "l2" | "cosine" | "dot" | "hamming";
+```
+
+Distance type to use to build the index.
+
+Default value is "l2".
+
+This is used when training the index to calculate the IVF partitions
+(vectors are grouped in partitions with similar vectors according to this
+distance type).
+
+The distance type used to train an index MUST match the distance type used
+to search the index.  Failure to do so will yield inaccurate results.
+
+The following distance types are available:
+
+"l2" - Euclidean distance. This is a very common distance metric that
+accounts for both magnitude and direction when determining the distance
+between vectors. l2 distance has a range of [0, ∞).
+
+"cosine" - Cosine distance.  Cosine distance is a distance metric
+calculated from the cosine similarity between two vectors. Cosine
+similarity is a measure of similarity between two non-zero vectors of an
+inner product space. It is defined to equal the cosine of the angle
+between them.  Unlike l2, the cosine distance is not affected by the
+magnitude of the vectors.  Cosine distance has a range of [0, 2].
+
+Note: the cosine distance is undefined when one (or both) of the vectors
+are all zeros (there is no direction).  These vectors are invalid and may
+never be returned from a vector search.
+
+"dot" - Dot product. Dot distance is the dot product of two vectors. Dot
+distance has a range of (-∞, ∞). If the vectors are normalized (i.e. their
+l2 norm is 1), then dot distance is equivalent to the cosine distance.
+
+"hamming" - Hamming distance. Hamming distance is a distance metric
+calculated from the number of bits that are different between two vectors.
+Hamming distance has a range of [0, dimension]. Note that the hamming distance
+is only valid for binary vectors.
+
+***
+
+### maxIterations?
+
+```ts
+optional maxIterations: number;
+```
+
+Max iteration to train IVF kmeans.
+
+When training an IVF FLAT index we use kmeans to calculate the partitions.  This parameter
+controls how many iterations of kmeans to run.
+
+Increasing this might improve the quality of the index but in most cases these extra
+iterations have diminishing returns.
+
+The default value is 50.
+
+***
+
+### numPartitions?
+
+```ts
+optional numPartitions: number;
+```
+
+The number of IVF partitions to create.
+
+This value should generally scale with the number of rows in the dataset.
+By default the number of partitions is the square root of the number of
+rows.
+
+If this value is too large then the first part of the search (picking the
+right partition) will be slow.  If this value is too small then the second
+part of the search (searching within a partition) will be slow.
+
+***
+
+### sampleRate?
+
+```ts
+optional sampleRate: number;
+```
+
+The number of vectors, per partition, to sample when training IVF kmeans.
+
+When an IVF FLAT index is trained, we need to calculate partitions.  These are groups
+of vectors that are similar to each other.  To do this we use an algorithm called kmeans.
+
+Running kmeans on a large dataset can be slow.  To speed this up we run kmeans on a
+random sample of the data.  This parameter controls the size of the sample.  The total
+number of vectors used to train the index is `sample_rate * num_partitions`.
+
+Increasing this value might improve the quality of the index but in most cases the
+default should be sufficient.
+
+The default value is 256.
