Button B beeps morse and records the milli second time stamp

Next make a buffered record of ON OFF button presses along
with the time stamps so that a non interrupt
function can determine which morse values have been entered.

This can then be displayed on the screen.

This is based on the PicoAirQ code atmo.

In the fututre there may be a microphone amplified and filtered
to only hear morse frquencies at audio. this pcb could then listen to morse
being played and decode it.
An RS-232 output could be used for logging to
other computers etc.
