- Implemented [unPhone](https://unphone.net/) v9 board
- Updated `.clang-format` to better reflect the intended code style
- Fix SD card compatibility issues for all boards (frequency wasn't set well)
- Moved `I2cDevice` class from CoreS3 board project to TactilityHeadless project
- Tactility configuration now has default empty lists for apps and services fields
- Fix for Launcher app: we don't need padding when showing it vertically
- Fix for I2cDevice read/write calls that checked for `esp_err_t` instead of `bool`
- Fix for TinyUSB init that checked for `esp_err_t` instead of `bool`
Remove dependencies M5Unified and M5GFX because:
- Sometimes the release doesn't even compile
- The amount of functions is too close to the limit (I recently had to remove some code/dependency to be able to make a build at all)
- Graphics performance issue since last update
- Touch screen performance issues (not perfect yet, but better)
- Compatibility issues with Tactility SPI/I2C versus M5Unified/M5GFX variants.
