Added macos arm64 Apple Silicon to CI (#296)

* Added macos arm64 Apple Silicon to CI

- Added missing python 3.10 metadata to setup.py

* Need all python versions in the matrix

* Fixing github action matrix syntax

* Changing MACOSX_DEPLOYMENT_TARGET for older python versions

- Technically no one would be running python 3.7 on M1 anyway

* Adding windows visualcpp build tools and updated cmake

* Increase max-parallel for all matrix builds

* yaml indent

* trying visualstudio2022-workload-vctools

* disabled everything but windows and added tunshell for debugging

* try older powershell

* trying again

* try python instead of powershell

* bash with wget

* Using old windows client on other side

* wrong way

* backwards

* :(

* urgh back to caveman debugging

- trying older windows runners

* try it again with extra build tools

* Reverting back to windows-2019 runner for windows builds
