docs: Update README Badges (#1083)

* Add to authors (including fixing ordering)

* [readme] Update badges

This should make it easier for users to identify key information such
as:

- Latest PyPI version.
- Development Status (PyPI classifier based)
- Supported python versions (PyPI classifier based).
- Licence (GitHub based)

* Update development status classifier

This project is pretty stable now
