Arrow-js uses brittle `instanceof` checks throughout the code base.
These fail unless the library instance that produced the object matches
exactly the same instance the vectordb is using. At a minimum, this
means that a user using arrow version 15 (or any version that doesn't
match exactly the version that vectordb is using) will get strange
errors when they try and use vectordb.
However, there are even cases where the versions can be perfectly
identical, and the instanceof check still fails. One such example is
when using `vite` (e.g. https://github.com/vitejs/vite/issues/3910)
This PR solves the problem in a rather brute force, but workable,
fashion. If we encounter a schema that does not pass the `instanceof`
check then we will attempt to sanitize that schema by traversing the
object and, if it has all the correct properties, constructing an
appropriate `Schema` instance via deep cloning.
This also renames the new experimental node package to lancedb. The
classic node package remains named vectordb.
The goal here is to avoid introducing piecemeal breaking changes to the
vectordb crate. Instead, once the new API is stabilized, we will
officially release the lancedb crate and deprecate the vectordb crate.
The same pattern will eventually happen with the npm package vectordb.
This PR adds the same consistency semantics as was added in #828. It
*does not* add the same lazy-loading of tables, since that breaks some
existing tests.
This closes#998.

This PR also reworks the table creation utilities significantly so that
they are more consistent, built on top of each other, and thoroughly
documented.
A `count_rows` method that takes a filter was recently added to
`LanceTable`. This PR adds it everywhere else except `RemoteTable` (that
will come soon).
Allow passing API key as env var:
```shell
export LANCEDB_API_KEY=sh_123...
```
with this set, apiKey argument can omitted from `connect`
```js
const db = await vectordb.connect({
uri: "db://test-proj-01-ae8343",
region: "us-east-1",
})
```
```py
db = lancedb.connect(
uri="db://test-proj-01-ae8343",
region="us-east-1",
)
```
Close#773
we pass an empty table over IPC so we don't need to manually deal with
serde. Then we just return the schema attribute from the empty table.
