When decoding NMEA sentences, sometimes values in a sentence are missing, no value is given, like `$GPVTG,,,,,,,,,N*30`. AvNav [decodes this](https://github.com/wellenvogel/avnav/blob/bcb1e4322d6013a4defc4cf94f926be4490b3436/server/avnav_nmea.py#L335) to `{'track': 0.0, 'speed': 0.0}`. IMHO this is wrong, because...
I recently had some exchange with the guys from https://www.yachtd.com/ about the calculation of true wind from apparent wind and course data in one of their products. >me: this means...
Here is a starting point to fix #347 - check for missing values in NMEA parser and omit then (do not set to zero) - added parsing of `DBK` and...

The direction formatter should be configurable to display angles in the ±180° range or the 0-360 range. Currently it shows the values as they are, even values >360 are possible.

First, thanks for this project! :tophat: related to https://github.com/wellenvogel/avnav/issues/367 and https://github.com/kdschmidt1/Sail_Instrument I noticed that the [gateway computes true wind](https://github.com/wellenvogel/esp32-nmea2000/blob/0bb6898d6e19a33ce1ef8cb15d02a0f15f521d8a/lib/nmea2kto0183/N2kDataToNMEA0183.cpp#L467) from COG/SOG and AWA/AWS, but I suspect the calculations not to...
