airspy: add support for AirSpy wideband receiver
Requires https://github.com/airspy/host Usage example: osmocom_fft -a airspy The following named gain stages are available: LNA: 0 to 15, step 1 MIX: 0 to 15, step 1 IF: 0 to 15, step 1 At the moment the gains are not in dB but gain indices internal to R820t tuner.wip-signat
