This includes a handful of minor edits I made while reading the docs. In
addition to a few spelling fixes,
* standardize on "rerank" over "re-rank" in prose
* terminate sentences with periods or colons as appropriate
* replace some usage of dashes with colons, such as in "Try it yourself
- <link>"
All changes are surface-level. No changes to semantics or structure.

Support hybrid search in both rust and node SDKs.
- Adds a new rerankers package to rust LanceDB, with the implementation
of the default RRF reranker
- Adds a new hybrid package to lancedb, with some helper methods related
to hybrid search such as normalizing scores and converting score column
to rank columns
- Adds capability to LanceDB VectorQuery to perform hybrid search if it
has both a nearest vector and full text search parameters.
- Adds wrappers for reranker implementations to nodejs SDK.
Additional rerankers will be added in followup PRs

Notes about how the rust rerankers are wrapped for calling from JS:
I wanted to keep the core reranker logic, and the invocation of the
reranker by the query code, in Rust. This aligns with the philosophy of
the new node SDK where it's just a thin wrapper around Rust. However, I
also wanted to have support for users who want to add custom rerankers
written in Javascript.
When we add a reranker to the query from Javascript, it adds a special
Rust reranker that has a callback to the Javascript code (which could
then turn around and call an underlying Rust reranker implementation if
desired). This adds a bit of complexity, but overall I think it moves us
in the right direction of having the majority of the query logic in the
underlying Rust SDK while keeping the option open to support custom
Javascript Rerankers.
We upgraded the toolchain in #1960, but didn't realize we hardcoded it
in `npm-publish.yml`. I found if I just removed the hard-coded
toolchain, it selects the correct one.
This didn't fully fix Windows Arm, so I created a follow-up issue here:
https://github.com/lancedb/lancedb/issues/1975
binary vectors and hamming distance can work on only IVF_FLAT, so
introduce them all in this PR.

Hi lancedb team,
This PR adds the `bypass_vector_index` logic to the sync API, as
described in [Issue
#535](https://github.com/lancedb/lancedb/issues/535). (Closes#535).
Iv'e implemented it only for the regular vector search. If you think it
should also be supported for FTS, Hybrid, or Empty queries and for the
cloud solution, please let me know, and I’ll be happy to extend it.
Since there’s no `CONTRIBUTING.md` or contribution guidelines, I opted
for the simplest implementation to get this started.
Looking forward to your feedback!
Thanks!

* Add `See Also` section to `cleanup_old_files` and `compact_files` so
they know it's linked to `optimize`.
* Fixes link to `compact_files` arguments
* Improves formatting of note.
* Upgrades our toolchain file to v1.83.0, since many dependencies now
have MSRV of 1.81.0
* Reverts Rust changes from #1946 that were working around this in a
dumb way
* Adding an MSRV check
* Reduce MSRV back to 1.78.0
### Changes to sync API
* Updated `LanceTable` and `LanceDBConnection` reprs
* Add `storage_options`, `data_storage_version`, and
`enable_v2_manifest_paths` to sync create table API.
* Add `storage_options` to `open_table` in sync API.
* Add `list_indices()` and `index_stats()` to sync API
* `create_table()` will now create only 1 version when data is passed.
Previously it would always create two versions: 1 to create an empty
table and 1 to add data to it.
### Changes to async API
* Add `embedding_functions` to async `create_table()` API.
* Added `head()` to async API
### Refactors
* Refactor index parameters into dataclasses so they are easier to use
from Python
* Moved most tests to use an in-memory DB so we don't need to create so
many temp directories
Closes#1792Closes#1932
