In #3631 this stub package has been a huge help in understanding pyarrow.

Wanted to split out this dev dependency change for visibility.

Also, the 1 minor change to satisfy mypy on a test:

tests\utils\test_utils.py:143: error: Argument 1 to "schema" has incompatible type "list[object]"; expected "Iterable[Field[Any]] | Iterable[tuple[str, DataType]] | Mapping[str, DataType]"  [arg-type]
