Use of deprecated pkg_resources #200
Description
I noticed this warning regarding pkg_resources in popping up in a notebook where we use pythia-datasets. It's also showing up in CI runs.
Relevant snippet from the logs:
/home/runner/work/pythia-datasets/pythia-datasets/pythia_datasets/__init__.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.
