Fixed
- `AttributeError` when passing `pandas.Timestamp`s with different timezones (*of which one was UTC*) to `DatapointsAPI.retrieve_dataframe_in_tz`.
- A `ValueError` is no longer raised when passing `pandas.Timestamp`s in the same timezone, but with different underlying implementations (e.g. `datetime.timezone.utc` / `pytz.UTC` / `ZoneInfo("UTC")`) to `DatapointsAPI.retrieve_dataframe_in_tz`.

Added
- Support for giving `start` and `end` arguments as `pandas.Timestamp` in `DatapointsAPI.retrieve_dataframe_in_tz`.

Improved
- Type hints for the `DatapointsAPI` methods.

Fixed
- Fixed a bug in `DatapointsAPI.retrieve_dataframe_in_tz` that could raise `AmbiguousTimeError` when subdividing the user-specified time range into UTC intervals (with fixed offset).

Fixed
- Fixed a bug that would cause `DatapointsAPI.retrieve_dataframe_in_tz` to raise an `IndexError` if there were only empty time series in the response.

Removed
- Removed support for legacy auth (API keys, service accounts, login.status)
- Removed the deprecated `extractionPipeline` argument to `client.extraction_pipelines.create`. Only `extraction_pipeline` is accepted now.
- Removed the deprecated `client.datapoints` accessor attribute. The datapoints API can only be accessed through `client.time_series.data` now.
- Removed the deprecated `client.extraction_pipeline_runs` accessor attribute. The extraction pipeline run API can only be accessed through `client.extraction_pipelines.runs` now.
- Removed the deprecated `external_id` attribute on `ExtractionPipelineRun`. This has been replaced with `extpipe_external_id`.

Changed
- Enforce that types are explicitly exported in order to make very strict type checkers happy.
