Latest updates not in Pypi, causing setuptools build to fail due to unsupported "description-file" in setup.cfg

[apollon-rii]

This PR correctly changed "description-file" to "description, however this PR did not up the project version, and therefore not reflected in PyPi.

Over the weekend setuptools removed support for "description-file" and broke A LOT of builds. Sounds like they are reverting, but you should probably correct this on your end anyway.
