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
* Set all decoders output to binary format
* Introduce the quadrature demodulation filter in all affected
flowgraphs, in order to reduce false alarms and increase performance
