AntiCat da05bc6eca Legic: rewrite reader to use xcorrelation and precise timing (#654) 
* Legic: rewrite reader to use xcorrelation and precise timing
 - Even tough Legic tags transmit just AM, receiving using
   xcorrelation results in a significantly better signal
   quality.
 - Switching from bit bang to a hardware based ssc frees
   up CPU time for other tasks e.g. prng and demodulation
 - Having all times based on a fixed ts, results in perfect
   rwd-tag synchronization without magic +/- calculations.
* hi_read_tx: remove jerry-riged hysteresis based receiver
- This feature got obsolete by a x-correlation based receiver.
* Legic: adjusted sampling to new ssp clock speed
- Sampling is 4 times faster and pipeline daly reduced to 1/4.
 The new code samples each bit earyler to account for the
 shorter pipeline. That introduced bit errors by leeking the
 next bit into the current one.
* Legic: average 8 samples for better noise rejection.
* Update CHANGELOG.md
