Merge #380

380: Mechanized Release Process r=pathunstrom a=astronouth7303

Implements a mechanized release process. Under this, the release process would be:

1. Go to GitHub Release pages
2. Look at the diff since last version, compile changelog
3. On the GitHub site, create a tag/release with the changelog and any other release notes
4. Cirrus CI is responsible for building and uploading to PyPI and GitHub

Additionally, dev releases are uploaded to PyPI test every time `master` is updated.

Version numbers are no longer explicitly listed in the repo, instead being calculated based on the git tags.

This code is a pretty direct copy from https://github.com/gqlmod/gqlmod (which is in part based on code that @duckinator wrote).

@nbraud originally proposed this for PPB.
