Upgrade dependencies

[Jacob-Stevens-Haas]

Hey Andy, I had a bit of laptop-repair musical chairs recently, which led me to discover some version issues in the dependencies. Are you ok with these changes?

• Python 3.10 needs pytest >= 6.2.4, but dev requirement currently <3.7. Version 7.2.2 most recent.
• scikit-learn needs >=1.1.0 or it raises warnings in recent scipy versions, but requirement currently set at <1.1. Version 1.2.2 most recent.

Tests all pass with pytest 7.0.0, scikit-learn 1.1.0 as well as most recent pytest 7.2.2, scikit-learn 1.2.2.

Great, thanks Andy!
