Incompatible with pandas 2.1.0: `AttributeError: module 'pandas.core.dtypes.dtypes' has no attribute 'PandasDtype'`

[burnpanck]

It appears that something moved inside pandas recently, and now pint_pandas cannot be imported anymore.

This is with pandas 2.1.0 (released today) and pint_pandas 0.4.0.

Full traceback:
