ble module merge

[kpwebb]

initial ble module integration using new notification services described in #15

[russbiggs]

After a couple unsuccessful attempts on BLU Android device, I got the BLE to connect and it seems to get the signal from the wheel but there is an exception thats printing out in the Debugger:

E/flutter (14407): [ERROR:flutter/lib/ui/ui_dart_state.cc(177)] Unhandled Exception: PlatformException(set_notification_error, error when writing the descriptor, null, null)

@kpwebb I've also pushed a fix on the Android manifest which didnt allow it to build for Android, i think this was something i did in a previous commit

[russbiggs]

I've tested this using the Pi and the SiliconLabs mc, same exception is thrown on both
