Python 3.11 wheels
Pre-emptive creation of an issue to release a set of Python 3.11 wheels, now that it's hit rc1. As of now we'd either do a 1.15.2 to include changes (since so far there have only been test changes to 1.15.1 to support 3.11) or just bring forward the test fix and build 1.15.1 wheels for 3.11.
