Add Mac OS support for Apple Silicon (#770)

* Made an install script and auto updates env for mac

* GPU sensors and initial training working for MAC. Still WIP.

* Switch dataloader to single threaded until I can work around some mac pickeling issues.

* Get quantization working on mac

* Fix mac exclusive imports so they don't break other builds.

* Add mac instructions to the UI
