- keys beep and haptic refactoring (not anymore audio events)
- trims move/mid/min/max refactoring (trim end splitted to trim min / trim max)
- S6R new alarms
- S6R servos/rx status displayed as a text (not an integer which has no sense)
- Timer countdown configuration
- The splash was not displayed (but the timeout was there) after the first calibration
I did a refactoring for the latitude and longitude decoding which should be tested carefully for FrSky S.PORT and D telemetry
There was a double conversion in S.PORT protocol, there are less maths now, and perhaps precision will be better
