NetCDF codec?

[jeandet]

There are some NetCDF files we might want to support.

• Which ones?
• is there any standard? (PDS, ISTP,...)

FYI, I just noticed that the ICON mission data from CDAWeb (https://spdf.gsfc.nasa.gov/pub/data/icon/) are in netCDF format with support for the ISTP standard (https://github.com/IHDE-Alliance/ISTP_metadata/blob/main/ISTP_metadata_guidelines/docs/example_mission_metadata_specifications.md#6-icon).
