MOM6 compatibility

[aekiss]

Should check whether this is compatible with MOM6 and update if needed.

FMS can actually support a YAML diag table natively: https://github.com/NOAA-GFDL/FMS/blob/main/diag_manager/diag_yaml_format.md

Other than that , I think the old format is the same between MOM5 and MOM6, since it comes from FMS and not the models themselves.

Thanks @angus-g!

The make_diag_table YAML format is designed to minimise repetition and facilitate automatic construction of meaningful filenames, e.g. to support one file per variable. The FMS YAML format seems to be designed with different objectives.

I can confirm what @angus-g suspected: diag_table generated by make_diag_table.py worked fine in a test run with ACCESS-OM3, so it looks like it's already compatible with MOM6.

Of course, while make_diag_table.py is general enough to handle MOM6, diag_table_source.yaml would need to be changed to account for the differing variable names and vertical remapping - see https://mom6.readthedocs.io/en/main/api/generated/pages/Diagnostics.html#native-diagnostics
