Description

Adds a deployment workflow.

• make a tag and it'll upload to testpypi, and then pull it down and run tests to make sure it all went well
• make a release from that tag and it'll upload to pypi and then pull it down and run tests to make sure it all went well

Status

• Ready to go

Will need to test it once it's merged.
