Remove serial cal commands, just log raw ADC on each value change

Browse Source 
- Print raw ADC + mapped MIDI value on every change
- Remove cal min/cal max serial commands (broken with multi-word)
- Keep cal_min=0, cal_max=4095 defaults
- User moves pedal full range and reports min/max raw values
