1.5.1 -- Fix KISS Framing Bug

This is a bug fix release to fix a KISS framing defect introduced when adding the BERT receiver.

BERT Receiver

BROKEN -- DO NOT USE -- USE 1.5.1 INSTEAD

• Version "1.5"
• Bit error test receiver implementation.

Firmware support in the TNC to send M17 BERT KISS frames is needed to make use of this new feature.

Version 1.4 -- ACCESS_FINE_LOCATION

• Add ACCESS_FINE_LOCATION to try to fix BLE connection issue.
• Add version number to screen.

These go to 11

• Update BLE communication handling to work better in background.
• Add notification on RX.

Fix Device Connection Handling

• Refactor USB handling into a service
• This fixes audio receive on USB connections
• Use a WAKE_LOCK to play audio in the background
• Update version number to 1.2
• Fix BLE connection handling

Note: When the application is in the foreground and connected, even with the screen off, it can play audio. This also means it will be consuming more power.
