Bug Description

When installing mattersim from package repository, the dependencies require a setuptools>=45 but as of version 82 and above they have removed pkg_resources which breaks the current implementation.

MatterSim Version

v1.2.0

Python Version

3.10

Reproduction Steps

1. Install mattersim from package repository like Pypi with nothing else installed on env constraining to setuptools<=82
2. import mattersim

Expected Behavior

Should import without issue by not depending on pkg_resources or constraining to a setuptools<=82

Actual Behavior

Error on import due to No module named 'pkg_resources'

Error Logs
