New releases not being published on PyPI

Hi, not sure if this is the right place for this, but I noticed on PyPI that the current release is from July 31, 2020. I think this means that when 'pip3 install cl-chess' is run, the version from then will be installed.

I haven't done it myself, but I know there's a way to sync up github with PyPI releases. E.g: https://www.youtube.com/watch?v=U-aIPTS580s
