lf Bug Fixes and lf demod additions

added data fskparadoxdemod
added data setdebugmode (for demods)
added data shiftgraphzero (to help clean weak reads)
fixed a few bugs with the data detectaskclock
added data fskfcdetect to detect FSK clocks
adjusted most of my demods to put raw tag binary to demod buffer for
future sim and clone commands (psk still needs work)
