Add release workflow, dynamic versioning (#30)

This PR:

- replaces the static version with a dynamic versioning plugin that
assigns versions based on git sha
- adds a release.yml that will publish to pypi when a new GitHub release
is published

Once we merge this we should create a git tag for 0.2.0 at the sha where
that version was bumped.
