Add a GitHub action to publish version upgrades (via setup.py) to PyPI

Releases are currently being done manually from local env when there is a new version. Would be nice to have a GitHub action to publish the package to PyPI when there is a commit to master (merged via PR or direct push) that contains a newer version of the package.
