fix bug in pskdemod return value if no samples...
... caused crash in data psknexwatchdemod if no samples were in the
graphbuffer.
also fixed hf mfu wrbl and rdbl to allow printing of help without a tag
being present.

Add PACE replay functionality
This function allows the user to specify APDUs which are sent to a card
supporting the PACE protocol. The response times are measured and
printed.
The code was pulled from the old Google Code repository (branch "epa")
and modified to fit into the new code base.

fixing iso14443b (issue #103):
- fix: IQ demodulator (FPGA)
- fix: approximately align reader signal delay to tag response delay (FPGA)
- fix: remove deprecated RSSI calculation to improve decoder speed (iso14443b.c)
- fix: better approximation of signal amplitude to avoid false carrier detection (iso14443b.c)
- fix: remove initial power off in iso14443b raw command (iso14443b.c)
- add: enable tracing for iso14443b raw command (iso14443b.c)
- fix: client crashed when checking CRC for incomplete responses (iso14433b.c)

the ECC signature is taken from a NTAG 215 tag. Might work.
