AIS binary message decoding for weather data

[KEGustafsson]

Would it possible to add more binary message decodings to case 8?

One interesting message could be meteorological-hydrographic-data to get weather observations from AIS where available.

Feel free to add it and to make a merge request. As you have a detail definition of the message, it should not be complex.

I'll make a PR from this.

Cool, I'm sure that it will interest other people as well.

Interested in this, Alaska has some weather broadcasts over AIS that I would love to catch.
