Mysu unofficial - beta builds are available - eviltoast

Hey folks, I finally got around to setting up [an extremely ugly, but nevertheless working] pipeline to automatically build Mysu (it only builds arm64 images for now, so they might not work if you have a very old phone. This probably shouldn’t affect many people, but if it does affect you and you would like to test Mysu - please let me know).
Testing and feedback is welcome :)
