Also cleans up Github Actions for exactly the same commands between OSes for running tests, creates a [testing_no_cython] option for installing, adds a no Cython environment for testing via Actions, and deletes the manualdeploy Action as the autodeploy is now working reliably (to minimize maintenance overhead of actions).
Primarily fixes #438.
