netsdr: add support for RFSPACE NetSDR receiver
- implements broadcast UDP based device discovery - prints device information (serial/versions) on startup - reads available frequency range(s) from the device - integrity checks of IQ stream using sequence numbers - automatic bandpass or a wideband lowpass selectable The following named gain stages are available: ATT: -30 to 0 dB, in 10dB steps Known limitations: - setting the sample rate is possible only before the flowgraph has been started
