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.

Note this currently the filter/where is only implemented for LocalTable
so that it requires an explicit cast to "enable" (see new unit test).
The alternative is to add it to the Table interface, but since it's not
available on RemoteTable this may cause some user experience issues.
https://github.com/lancedb/lancedb/issues/623
Fixes issue trying to print response status when using remote client. If
the error is not an HTTP error (e.g. dns/network failure), there won't
be a response.
This PR upgrade lance to `0.7.5`, which include fixes for searching an
empty dataset.
This PR also adds two tests in node SDK to make sure searching empty
dataset do no throw

aws integration tests are flaky because we didn't wait for the services
to become healthy. (we only waited for the localstack service, this PR
adds wait for sub services)
# WARNING: specifying engine is NOT a publicly supported feature in
lancedb yet. THE API WILL CHANGE.
This PR exposes dynamodb based commit to `vectordb` and JS SDK (will do
python in another PR since it's on a different release track)
This PR also added aws integration test using `localstack`
## What?
This PR adds uri parameters to DB connection string. User may specify
`engine` in the connection string to let LanceDB know that the user
wants to use an external store when reading and writing a table. User
may also pass any parameters required by the commitStore in the
connection string, these parameters will be propagated to lance.
e.g.
```
vectordb.connect("s3://my-db-bucket?engine=ddb&ddbTableName=my-commit-table")
```
will automatically convert table path to
```
s3+ddb://my-db-bucket/my_table.lance?&ddbTableName=my-commit-table
```
- Supports creating an empty table as long as an Arrow Schema is provided
- Supports creating a table from an Arrow Table (can be passed as data)
- Simplified some Arrow code in the TS/FFI side
- removed createTableArrow method, it was never documented / tested.
Previously when logging the `LocalConnection` and `LocalTable` classes,
we would expose the aws creds inside them. This PR changes the stored
creds to a anonymous function to hide the creds
BREAKING CHANGE: The `score` column has been renamed to `_distance` to
more accurately describe the semantics (smaller means closer / better).

- Callers / SDKs are responsible for keeping track of the last version of the Table
- Remove the mpsc from Table and make all Table operations non-blocking
- Implement Result/Error in the node FFI
- Implement a trait (ResultExt) to make error handling less verbose
- Refactor some parts of the code that touch arrow into arrow.rs
