Auto install Examples and Samples directories at startup

Automatically creates Samples and Example directories if not present and copies files into persistent storage. Just install the apk and run and you should be good to go now. Experiment with velocity feature from jarity fork on drums. Shutdown all sound before exiting to avoid stutter when quitting.

But a lot is still not working...but it's still pretty cool.
Camera is not working, I think HDR broke it, eventually may try to hook it up to Chromecast directly, the built in Oculus broadcast will not work as it will only do the main display and not an alternate camera.
Video Player is not working, Unity interface changes, needs to be refactored.
Some controller actions are not working, needs a quest controller model.
MIDI does not work, not sure what options there are on Android for this yet.
audio performance is not great with lots of samples playing and the graphics overhead and you may get stutter
other stuff is not working, I will spend time on this after everything is working.
