initial support for Noctigon KR4
  (not complete, but far enough that it installs and runs)
New hardware support features:
  - allow using PCINT other than 0 (PCINT1, PCINT2, etc)
  - option to ignore voltage ADC while the button is pressed
    (because my prototype shorts the voltage divider to 0 while the button is down)
