pkg_resources to be deprecated #360
Description
I just noticed this warning running afew:
/opt/homebrew/lib/python3.13/site-packages/afew/FilterRegistry.py:4: UserWarning: pkg_resources is deprecated as an API. See https://setuptools.pypa.io/en/latest/pkg_resources.html. The pkg_resources package is slated for removal as early as 2025-11-30. Refrain from using this package or pin to Setuptools<81.
It seems to be used only in FilterRegistry.py as all_filters = FilterRegistry(pkg_resources.iter_entry_points('afew.filter')) and in conf.py in release = get_distribution('afew').version.
