This validates expressions that are passed into functions of the relational api.
This solves a long standing bug where pybind calls DECREF on a _static_ py::object during interpreter shutdown, which is too late.
Related duckdb#37 Two small code fixes: * Add support for native `StringDType` * Fixes scope bug in lazy attribute reading in ConvertDateTimeTypes Support for `timedelta64[s|ms|us|ns]`: * Where Pandas used to only support timedelate64[ns], Pandas 3 now infers the resolution. We added support for reading all of the new types. * We now output timedelta[us] whenever timedelatas are read from DuckDB, since that is DuckDB's own resolution. **This is a breaking change.** Pyproject.toml updates: * env markers to allow higher version of dependencies (pandas, pyarrow and adbc-driver-manager) Lots of changes to tests: * Removes the ArrowPandas and NumpyPandas helpers. We will now test using whatever default backend for almost all tests, which makes most sense for regular values. * We do still test arrow dtypes, but we now do so explicitly. * Support both `zoneinfo.ZoneInfo` objects (3.0.0 and up) and `tzdata` (before) Also see: - [Migration Guide](https://pandas.pydata.org/docs/dev/user_guide/migration-3-strings.html#string-migration-guide) - [Changelog](https://pandas.pydata.org/docs/dev/whatsnew/v3.0.0.html)
