Fixes#2275
Adds `Joystick.use10bit` and `Joystick.use16bit` methods. 10-bit is
unsigned from 0...1023 while 16-bit is signed -32767..32767.
Defines a new HID descriptor to support the increased resolution.
* Adapted all libraries to support multiprotocol HID over BT & BLE
* Added ATT DB depending on setup; still no success with working connection
* Added hids_device from BTStack develop branch as override
* Fixing the GATT handle patching, added working ATT DB
* ran astyle on example
* Updates in BLE implementation; WORKING! (but only if all are activated). Removed sdkoverride again, doesn't work.
* Moved ATT DB handles to correct places
* Finally functioning for Mouse+KBD+Joy, and each individual
* Cleaned up code & ran astyle
* Added sdkoverrides to pull develop functions from BTSTack
* Changed a few typos by BTStack to run codespell successfully
* Ran astyle on sdkoverride files
* Added some #if guards for including BTSTack file only if BT is enabled
* Fixed Feature Report value characteristics handle assignment; fixed too long HID report
* Ran astyle
Allow sending thigns like KEY_MUTE or KEY_SCAN_NEXT from the USB and
Bluetooth Classic keyboard libraries.
BLE requires some add'l magic, not yet discovered.
Pull in latest upstream Keyboard library changes
Move the Joystick, Keyboard, and Mouse into a base class which handles
the operation/input, and a subclass which will implement the reporting
as a HID device via USB, Bluetooth Classic, or Bluetooth Low Energy (BLE).
Reduce copies of library code and makes maintainability much better.
