replace deprecated pkg_resources with importlib.resources

[zacharyburnett]

pkg_resources is deprecated and was recently removed from setuptools>81

This change replaces usages of pkg_resources with importlib.resources (see https://importlib-resources.readthedocs.io/en/latest/migration.html)

oh sorry I forgot to ping @hover2pi 😅

Just adding a quick note to say that the motivation behind this is the updating of the packaging and testing for Mirage, which surprisingly, still has a few users. Some solar system folks are using it to insert fake asteroids/TNOs into their data in order to measure recovery rates vs magnitude.

Merged! Thanks for the fix @zacharyburnett !

[zacharyburnett]

great! If we can get a new release to PyPI then this will solve our dependency issue 😄
