Support for other platforms

[micrusa]

Add support for other platforms like other full android watches and WearOS support

• Don't use amazfit code when device is not an amazfit
• Check if sensors like heart rate and accelerometer are present before showing up that features
• Make all layouts relative to support any watch with a good design
• Build for WearOS

Progress:
Running correctly on even Q phones, so it should work fine on all full android watches, all amazfit code isn't being run on other devices. Still need to make layouts more relative to the screen size and shape
