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
Optimized Assembly code saving more bytes and saving a few cycles
Moved and refactored assemby from ATMlib.h code to ATMlib.cpp
fix muteChannel() and unMuteChannel() so (un)mutes channel properly
Added C++ equivalent ISR code
Timer/counter 4 is enabled on Arduino init() and a Timer/counter 4 overflow may happen right after the timer/counter 4 interrupt is enabled. When this happens the channels have not been initialized yet causing random noise/sounds being played.
This has been fixed by moving the interrupt enable after the channels have been initialized.
