hackrf_sweep: Added experimental Inverse FFT binary output mode.
...
In this mode, FFT output bins from multiple hops are stitched together into a
single set of bins per sweep. Each sweep is then processed with an inverse FFT
to simulate a time domain signal at a sample rate equal to the sweep bandwidth.
This wideband time domain signal is sent to the output as complex floats and
can be piped to or viewed with tools such as fosphor or inspectrum. The output
signal is discontinuous, so the time axis (e.g. in inspectrum) will be
incorrect.
