New beta this time with focus on the new Gravitymon PCB and the Waveshare ESP32c3 Zero

New features

Added PCB for Waveshare ESP32c3 zero (18-pin board)
Added feature flags to build so builds can be customized and UI will better adapt.
Added RAPT bluetooth transmission covering both v1 and v2 formats.
Added instructions for Grainfather integration.
Added timeouts to the i2c bus and improved error handling when timeout occurs during hardware scan.
Added support for Waveshare ESP32c3 zero (18-pin board)
Refactored UI code to reduce the size and simplify maintenance (30% size reduction)
Added charging pin feature so that device can go to deep sleep when charging.
Updated documentation to match the current features
Added more debug output to MPU6050 calibration sequence to help troubleshooting gyro issues.

Dropped features

Support for ESP32lite/Floaty and ESP32 d1 mini has been dropped. Latest version is v2.2. This to remove these boards that are quite old and make room for new options.
Remove the gyro disabled flag which was used to run the device as a temperature probe only. Latest version is v2.2

Fixed startup issue after deep sleep on some boards when RTC_MEM was enabled.
Fixed issue that temperature sensor was not recognized when gyro had no valid values.
Corrected R1 + R2 on Gravitymon PCB to 10k so wakeup after charger removed works correctly.
