Synchronise the data format definitions with the parsing tools

Automatically synchronize the data format definitions with the parsing tools.
Relevant after #1 or #3 is solved

I have this preliminary code in the prototype of ragali for checking if a file conforms to the standards. If we do a "release" in this repos to add versioning, this tool could also be extended to allow checking different version of the data format.

We should probably not overdo it with releasing new version of the data format since it does not make much sense to have ten different iterations each year, resulting in many different possible versions that individual NetCDFs comply with.

Regarding the naming of the versions of our data format conventions, I suggest to follow the "semver" style https://semver.org/
