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
To allow easier integration to the new architecture the
multi format file sink supports bot legacy and the new
format of the PMT messages. In poth cases, only the PDU
is extracted. Legacy used the PDU as a BLOB, whereas
now the PDU is stored in base64 format inside a
dictionary, which structure is defined through
the gr::satnogs::metadata() class
* AFSK1200 decoder with AX.25 frame support
* Fix issue with the AX.25 decoder when the frame has only one AX.25
SYNC flag
* Fix clear text debug output to print each one of the characters and
not the string, so that the payload can be partially be printed even if
it contains non-printable characters
* Add AFSK1200 decoder example that can decode frames from an .ogg file
