Develop code to convert NcML to Kerchunk JSON?

[rsignell-usgs]

The NetCDF Markup Language (NcML) has been widely used for decades to create virtual NetCDF datasets that point to collections of NetCDF files and add/modify global and variable metadata and/or values.

It would be very useful to have a package that parses this info from an NcML XML file and generates the equivalent Kerchunk JSON virtual dataset.

A fairly complicated example of NcML that aggregates a collection of ROMS NetCDF files and makes them CF and SGRID compliant is here:

Starting with the easy example!

Worth saying, is that this would allow us to make use of the effort already put into these NcML prescriptions, to provide aggregate (multi-file) datasets without needing a thredds or any other server.
