BUG v2.23.0 - PGN 129285 - Defect - wpLatitude: null - allways.

Hi,

I am trying to implement a plugin for the furuno autopilot NavPilot-711c/700.
Sniffing the n2k traffic I see that TZ Pro sents the pgn 129285, but it seems not to be implemented here.

  "pgn": 129285,

    ]

Thanks for the merge of PR 121, that brings us a big step forward. What I couldn't see is that the PGN sent are all "wpLatitude": null,.

I have a fork of Canboat Visual Analyzer, that allows to see the transmitted PGNs also.

I have sent a PR to sBender.

I will now fork this too and see if I can fix this and sent you a PR.
