Start working on the basics of the AT3x04 decoding module.
Refine the code used for detecting AT3x04 waveforms and aligning the
program to decode them.
Tidy up the AT3x04CarrierConfirm() method code.
Add the populateCarrierTonesBins() method and tidy the code. Will merge
this branch back into the master now and return to work on this mode at
a later date.
