fix hf mf sim

Browse source 
* use DMA to receive reader command
* switch earlier from send to listen mode
* move ADC initializer to iso14443_setup
* remove remainders of incomplete Mifare 10Byte UID simulation
* show 'short' bytes (7Bits or 8Bits without parity) in 'hf list mf' and 'hf list 14a'
* whitespace
