* fix debug print on unhandled commands
* deduplicate: use sim functions from iso15693.c
* fix times in tracelog and 'hf list iclass' (sim only)
* don't check parity in 'hf list iclass'
* fix timing in TransmitTo15693Reader()
* merge hf_rx_xcorr and hf_tx modes into one module with common ssp_clk and ssp_frame
* get rid of most of the warnings when compiling the HF verilog sources
* refactoring the constants in Verilog sources
* Add raw HF signal plotting
* new fpga module hi_get_trace.v - store A/D converter output to circular buffer on FPGA
* new command 'hf plot' - pull data from FPGA and display it in Graph Window
* fixing hf 15: implement hf 15 snoop
* rename hf 15 record to hf 15 snoop
* speedup sampling / decoding:
* new FPGA mode FPGA_HF_READER_RX_XCORR_AMPLITUDE implements amplitude(ci, cq) on FPGA
* inlining the decoders in iso15693.c
* inlining memcpy/memset in LogTrace()
* giving up the moving correlator for SOF in Handle15693SamplesFromTag
* decode more of EOF in Handle15693SamplesFromTag()
* some refactoring
* added ISO15693 coding for tag messages (CodeIso15693AsTag())
* added ISO15693 decoding for reader commands (Handle15693SampleFromReader())
* send tag inventory response in either high or low speed
* some refactoring and formatting
* implement a real time Decoder for tag responses (will be required for sniffing)
* switch off field after each command (protect rdv40)
* correctly signal field status with LED D
* rework iso14443b device functions
* hf_read_rx_xcorr.v: transfer i/q pair in one 16bit frame
* hi_read_tx.v: invert ssp_dout. When nothing is transferred (ssp_dout=0), this results in no modulation (carrier on)
* adjust arm sources accordingly
* iso14443b.c: switch off carrier after hf 14b sri512read and hf 14b srix4kread
* iso14443b.c: fix DMA circular buffer handling
* ISO15693 device side improvements
* increase accuracy by doubling the sample frequency (hi_read_rx_xcorr.v)
* adjust armsrc/iso15693.c and client/cmdhf15.c accordingly
* use more accurate approximation for sqrt(ci^2 + cq^2)
* improve EOF detection (was often mistaken for Logic0, resulting in "error, uneven octet! (extra bits!)")
* hi_read_r_xcorr.v: avoid overflows during accumulation and truncation
* explicitely cast unsigned ADC samples to signed
any memory from BigBuf[]. This is required because FpgaDownloadAndGo() might
allocate, use, and free most of BigBuf[] when decompressing FPGA configs.
- cleanup: remove rests of deprecated "end of trace markers" (0x44)
CHG: USB_CMD_DATA_SIZE is now used as maxsize for transfer of data between client and pm3device
CHG: suggested a fix for the underscore problem in ioclass\fileutils.c
ADD: tnp3xx support
ADD: nxp tag idents.
ADD: identifiction of chinese backdoor commands to hf 14a reader.

you find issues here!
