pkg_resources is deprecated #1945
Description
We're seeing this warning in OTIO CI builds recently. It looks like we need to switch from pkg_resources to mportlib.resources or packaging instead.
/opt/hostedtoolcache/Python/3.12.11/x64/lib/python3.12/site-packages/opentimelineio/console/otioconvert.py:14: 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.
