Clickhouse-connect

Bug Fixes
- Changed type hint of the `query` parameter in Client `query*` methods to `Optional[str]` to work correctly with type analyzers.
This also highlights that using a query_context instead of a query in these methods is supported (and preferred for repeated queries).
Thanks to [Avery Fischer](https://github.com/biggerfisch) for the PR!
- Fixed sending a full table name to the `insert_file` tools function. Closes https://github.com/ClickHouse/clickhouse-connect/issues/305

Breaking Change
- Python 3.7 builds are no longer part of the wheels deployed to PyPI

Bug Fix
- Due to a change in default ClickHouse settings, inserts with "named" Tuple types no longer worked with ClickHouse
version 24.1 and later. This has been fixed.

Improvements
- Some types of security and other proxies require additional query parameters on any call to ClickHouse server behind
such a proxy. Because the HTTPClient makes certain initialization queries to ClickHouse before any query parameters
are set, it was difficult or impossible to create a Client successfully. You can now modify the HTTPClient class level
properties `params` and `valid_transport_settings` before calling `get_client` so that such "special" query parameters will be
included even on initialization queries. Thanks to [Aleksey Astafiev](https://github.com/aastafiev) for highlighting
the problem and contributing a PR.
- In some cases the user make want to disable urllib3 timeout settings `connect_timeout` and `send_receive_timeout` by
setting them to none. The same PR from Aleksey Astafiev now allows setting to values to `None`
- Update to Cython 3.0.8

Bug Fix
- Add missing Nothing SQLAlchemy datatype, which fixes some edge case Superset queries.
