Added Bluetooth support.
What works so far:
-> Sticks
-> Axis triggers
-> Stadia button recognised as Xbox button.
-> Options button is mapped to View (Back on 360) button.
-> All other buttons mapped to their Xbox counterparts.
-> Vibration motors over USB
-> Bluetooth mode
What doesn't work:
-> Vibration motors over Bluetooth - Broken in this release.
-> Assistant & Capture buttons - They don't have an Xbox counterpart but it might be possible for them to trigger something else useful.
Important: To avoid double input issues, you should use HidHide and follow the instructions in README.md.
