Update the obsolete flowgraphs and update the existing with
the new decoding architecture blocks. Client should
not have big problems with the new decoders as we utilizing
the multiformat frame sink that takes care of it. This
is just a work around for testing as we move forward for
fully socket-based communication with the client
All flowgraphs now support user defined parameters for most of their
configuration capabilities. These include:
* RF gain
* IF gain
* BB gain
* Custom device arguments for setups with multiple SDRs. These
coresponds to the 'Device arguments' field of the Osmocom source block.
* Antenna selection for devices with multiple antennas (USRPs, etc)
Changing sampling rate is not supported (yet).
For listing the arguments just execute <flowgraph> --help in a terminal
window.
fm_demod script that also writes waterfall data (credit to surligas, I'm just committing)
Also FFT needs to be added to CMakeLists.txt to build in some conditions.

Taking out WBFM/NBFM for a straight quadrature demod method
Change from 44.1k output to 44k output to be more compatible
with gr-satellites
Also changing rtlsdr to a 2msps rate by default
The FM demodulator now supports a variaty of hardware setups and saves
the WAV file for further processing. A set of command line arguments can
control most of the flowgraph internals, such as the wav file name and
storage path e.t.c.
TODO: Check the settings for all the available hardware
