Remove obsolete flowgraphs 

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
