Fix tests on python3.11, run tests in CI

[ahornby]

The Key enum was serializing via str() incorrectly on python 3.11, problem was a mix of usage of scc's own enum and the python stdlib enum, which changed in 3.11 (see https://github.com/python/cpython/issues/94763 )

There was only one reference to the stdlib enum so updated it to call the scc one (removing the scc specific enum.py is left for a future change, would make this one harder to review)

Added a test for Key str() and a github actions CI

I was going to submit a different fix for this that doesn't rely on the bundled enum implentation.

Thank you for the changes. Taking some time today to tinker with this source code.
