hitag1/S trace: add crc check

Browse source 
Example:

[usb] pm3 --> trace load -f traces/lf_HitagS256_dump.trace
[+] loaded 272 bytes from binary file traces/lf_HitagS256_dump.trace
[+] Recorded Activity (TraceLen = 272 bytes)
[?] try `trace list -1 -t ...` to view trace.  Remember the `-1` param
[usb] pm3 --> trace list -t hitags -c
[=] downloading tracelog data from device
[+] Recorded activity (trace len = 272 bytes)
[=] start = start of start frame end = end of frame. src = source of transfer
[=] Hitag1 / Hitag2 / HitagS - Timings in ETU (8us)

      Start |        End | Src | Data (! denotes parity error)                                           | CRC | Annotation
