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.
