update Arduboy and Arduboy2 libs 

Arduboy lib:
added support for Noritake GU128X64-800B VFD display

Arduboy2 lib:
added support for Noritake GU128X64-800B VFD display
removed experimental batterycheck code and keywords
temporary reverted assembly code in sprites.cpp
fixed one off bug in drawBitmap
buttonsState no longer uses timer ISR code
exitToBootloader function uses timer ISR code
