An ITU-T G.9959 (de)modulator for Z-Wave (started as a fork of andersesbensen/rtl-zwave). `wave-in` decodes Z-Wave frames from a raw I/Q stream piped in from an RTL-SDR (`rtl_sdr`) or HackRF; `wave-out` encodes frames and transmits them through `hackrf_transfer`. The rtl_433-style entry point for getting Z-Wave packets off a cheap SDR.
