unPhone implementation and more (#169)
- 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`
