Deprecation warning on installation

[ftclark3]

Warning text:

DEPRECATION: Legacy editable install of openawsem==1.1.0+121.gd60f7ec from file:///home/fc36/openawsem (setup.py develop) is deprecated. pip 25.0 will enforce this behaviour change. A possible replacement is to add a pyproject.toml or enable --use-pep517, and use setuptools >= 64. If the resulting installation is not behaving as expected, try using --config-settings editable_mode=compat. Please consult the setuptools documentation for more information. Discussion can be found at pypa/pip#11457

We should change setup.py to pyproject.toml
