Removed continuous fire and slow fire modes

Removed these modes because they're no longer needed for the project

 * D27 - Single pulse armed pin. toggles the armed state when it recieves a falling signal
 * D28 - Single pulse enable pin (A FALLING signal toggles single pulse mode)
 * D29 - Single pulse trigger. (LOW will cause the arduino to send 1 waveform pulse)

 * D31 - Armed state indicator light output
