* 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
