Test on Python 3.11

The Faster CPython Project is already yielding some exciting results. Python 3.11 is up to 10-60% faster than Python 3.10. On average, we measured a 1.22x speedup on the standard benchmark suite. See Faster CPython for details.

• [x] scipy-1.9.1 is incompatible with Python 3.11. scipy/scipy#16851 --> scipy-1.9.2!!
• [x] Install libopenblas-dev on pre-release versions of Python. Scipy pre-release seems OK.
• [ ] Next step is mdtraj/mdtraj#1752
