GitHub Action for publishing new package

[adamghill]

It would be nice to have an automated workflow for publishing a new package. Maybe based on creating a GitHub release which updates CHANGELOG.md, tags a new release, pushes to PyPI?

Will need some research to determine the best approach.

Hey @adamghill, I've set this up before (for npm and dart) triggering off the github release command. What are the current steps to creating a release?
