Using the current code on Python 3.11 does not seem to have a problem, so I just modified the CI, setup.py, and tox.ini.
Mocks were introduced to remove the dependency on graphix_ibmq during testing.
Currently, when running the PatternRunner test, graphix_ibmq is imported to see if PatternRunner works correctly. This strategy for testing checks the functionality of PatternRunner and graphix_ibmq at the same time, so when an error occurs, it is difficult to tell whether the problem derives from PatternRunner or graphix_ibmq. Also, because graphix imports graphix_ibmq and graphix_ibmq imports graphix, the test will not work correctly until graphix_ibmq supports Python 3.11. It is not ideal to encounter this issue every time graphix adds support for a newer Python version, so I avoided it by running the test assuming that graphix_ibmq is working correctly during testing.
