This commit adds GRCC into the CMake build system and creates the
executables from the .grc files on demand.
Because there is always the case that the gr-satnogs has not
been installed yet in the system, we still ship the auto-generated
from our side executables. In next releases, during the install
target, the GRCC and the executables generation, will be called
after the gr-satnogs is installed.
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
