[netcdfgroup] Read NASA CDF files with netCDF code - NetCDF Expansion Pack 1.3.0 release

Howdy all!

I've just released a new version of the NetCDF Expansion Pack - in it I add
a reader for NASA CDF data.

NASA CDF format is used for some NASA missions, and the CDF reader allows
such files to be read as if they were netCDF files.

Get the release here:

Feedback and comments welcome!

Keep on netCDFing!
