Filter and convert incomming NMEA messages

[olewsaa]

Excellent, I did not look for this protocol in the SignalK server, it came as no surprise that it's now included, many thanks to the implementers.
This is the way to go, I'm upgrading from RPi3 to RPi4 over the winther and this is the path forward.
I have a tablet velcroed to the bulkhead displaying "intrument panel" app. Cool when the laptop (VNC RPi) is closed.

I'm really happy with the progress of OpenPlotter and SignalK.
