This changes `lancedb` from a "pure python" setuptools project to a
maturin project and adds a rust lancedb dependency.
The async python client is extremely minimal (only `connect` and
`Connection.table_names` are supported). The purpose of this PR is to
get the infrastructure in place for building out the rest of the async
client.
Although this is not technically a breaking change (no APIs are
changing) it is still a considerable change in the way the wheels are
built because they now include the native shared library.
Sometimes LangChain would insert a single `[np.nan]` as a placeholder if
the embedding function failed. This causes a problem for Lance format
because then the array can't be stored as a FixedSizedListArray.
Instead:
1. By default we remove rows with embedding lengths less than the
maximum length in the batch
2. If `strict=True` kwargs is set to True, then a `ValueError` is raised
if the embeddings aren't all the same length

* Refactors the Node module to load the shared library from a separate
package. When a user does `npm install vectordb`, the correct optional
dependency is automatically downloaded by npm.
* Add scripts and instructions to build Linux and MacOS node artifacts
locally.
* Add instructions for publishing the npm module and crates.

- Core rust library
- ffi bridge that exposes rust functionality to javascript
- npm package that provides a TypeScript / JavaScript library
- limitations: it only supports reading for now
