Fix USB MIDI, add LED startup animation, improve logging

Browse Source 
- Use ArduinoUSBMIDI library for proper USB MIDI device recognition
- Add LED startup colour cycle (red, green, blue, yellow, magenta, cyan, white)
- Add comprehensive console logging for all MIDI in/out and switch events
- Log unmapped MIDI messages
