6a1f2d82bb bugfixes iso14443a (hf 14a commands)
- buffers were too small to handle 256 byte frames
- parity bits were only handled for up to 32 byte frames
- trace format was inefficient
- removed parity calculation from decoders in iclass.c (parity not used on air anyway)

baeaf57950 fix/add support for 4K (and other non 1K) card sizes in hf mf commands
- hf mf rdsc (fix): didn't account for 16 block sectors, allowed max sector 63 instead of 39
- hf mf ecfill (add): added (optional) card size parameter and support for non 1K cards
- hf mf dump (add): added (optional) card size parameter and support for non 1K cards
- hf mf dump (fix): Access Condition 011 not handled correctly (tried to access with key A)
- hf mf restore (add): added (optional) card size parameter and support for non 1K cards
- hf mf nested (fix): didn't account for 16 block sectors, allowed max sector 63 instead of 39
- hf mf nested (fix): always dumped 16 keys to dumpkeys.bin instead of correct number
- hf mf chk (fix): always dumped 16 keys to dumpkeys.bin instead of correct number
- hf mf eget (fix): displayed three instead of one block
- hf mf eload (add): load 4K .eml files (but accepts 1K .eml files for backwards compatibility)
- hf mf esave (add): always save the whole emulator memory (4K) instead of 1K only
- hf mf ecfill (add): added (optional) card size parameter and support for non 1K cards

- changed help text for hf mf dbg
- fixed minor bugs in help texts for hf mf sim and hf mf ecset
- display "key A" or "key B" instead of "key=0" or "key=1 in hf mf sim

991f13f27d minor bugfixes to hf mf sniff and hf 14a snoop
- tracing was not always enabled when starting hf mf sniff or hf 14a snoop
- ATQA was displayed in wrong byte order in hf mf sniff
- 4 Byte UIDs were displayed as 7 Byte UIDs (padded with 0x000000) in hf mf sniff
- same for logfile names.
- assignment (=) had been used instead of == in comparisons (shouldn't have been relevant though)

3b2fee43ea New LF edge detection algorithm + lowpass filter
This is a new LF edge detection algorithm for the FPGA.

- It uses a low-pass IIR filter to clean the signal
(see https://fail0verflow.com/blog/2014/proxmark3-fpga-iir-filter.html)
- The algorithm is able to detect consecutive peaks in the same
  direction
- It uses an envelope follower to dynamically adjust the peak thresholds
- The main threshold used in the envelope follower can be set from the ARM side

fpga/lf_edge_detect.v,
fpga/lp20khz_1MSa_iir_filter.v,
fpga/min_max_tracker.v: New file.

fpga/lo_edge_detect.v, fpga/fpga_lf.v: Modify accordingly.

armsrc/apps.h (FPGA_CMD_SET_USER_BYTE1,
FPGA_CMD_SET_EDGE_DETECT_THRESHOLD): New FPGA command.
fpga/fpga_lf.v: Modify accordingly/Add a 8bit user register.

fpga/fpga_lf.bit: Update accordingly.

fpga/tests: New directory for testbenches

fpga/tests/Makefile: New file. It compiles the testbenches
and runs all the tests by default (comparing with the golden output)

fpga/tests/tb_lp20khz_1MSa_iir_filter.v,
fpga/tests/tb_min_max_tracker.v,
fpga/tests/tb_lf_edge_detect.v: New testbenches

fpga/tests/plot_edgedetect.py: New script to plot the results from
the edge detection tests.

fpga/tests/tb_data: New directory for data and golden outputs
