Can you supply the updated udp message structure with the new field(s).
Thanks

Hi,
This patch adds itone data to the status message packet.
This feature is useful for 'digital transceivers' as they NO longer need
to rely on the AFP-FSK technique, which introduces a non-zero error into
the transmitted tone values.
While this approach is not as transparent as the AFP-FSK technique, it
eliminates the non-zero error associated with AFP-FSK.
As an alternate approach, the 'digital transceivers' can use ft8_lib
to derive the tones from the 'm_currentMessage' data, which is already a
part of the status message packet. However, ft8_lib is currently unable
to handle all the possible types of input messages.

Testing notes:
This patch was tested with following software:
- https://github.com/bmo/py-wsjtx software
- https://github.com/kholia/py-wsjtx (can show 'itone data')
A packet capture file (.pcapng) which has samples of the new UDP status
message packets in it can be found at the following URL:

Thanks for your time, and attention.
