Legic: Moved card simulator into separate file & cleaned interface.

Browse source 
Reader and card simulation have almost no common code. Moreover the sim
uses an SSP Clock at 212kHz for all timings to prevent any drifting from
the PRNG. This clock speed is not available in reader simulation mode (SSP
runs at up to 3.4MHz, and changes speed between TX and RX). For these
reasons having the code in separate files makes it significantly cleaner.
