add: start to support Topaz tags
- hf 14a reader now exits gracefully in case of proprietary anticollision sequence
- changed miller decoder to handle Topaz 8 data bits/no parity frames from reader
- started to implement hf list topaz
Implemented the correct way to calculate MAC from a tag, feeding it an extra 32 zeroes. Also divided it up into two parts, one of which can be precalculated by the device before the simulation begins

lf simulation tests
added SimulateTagLowFrequencyTest function
with some adjustments that help ASK simulations
FSK and PSK still need help. Left original HID sim alone as for some it
may partially work.
Further implementation of iclass 'fullsim'. Moved protocol definitions to shared file. Had to add some loclass-function to arm-side to support authentication in fullsim mode
Implemented 'hf iclass decrypt <tagdump>'. This performs the 3des decryption of iclass tag dumps, but requires the decryption file to be present on the filesystem
