lf viking build / lf awid refactor / lfdemod.c debugMode==2

lf viking from other users - just put my spin on it
lf awid refactored code - possible to make it not 26bit specific now
with minor chanages
lfdemod.c now supports extra debug printing if `data setdebug` = 2 when
not on device (on client not arm)
