marshmellow42 1fbf895616 lf updates
applies icemans full ata55x7 read/write settings
adds checksum to ioprox (thanks to iceman)
adds silent mode for lf read and getSamples
fix lf em em410xwatch and lf em410xspoof
improve data rawdemod ar -  for biphase demods
improve detectclock a for strong antennas
