[netcdfgroup] version 3.0 of the NetCDF Expansion Pack: access to medical images with DICOM reader

Howdy all!

Recently I released version 3.0 of the NetCDF Expansion Pack (NEP). The NEP
provides:
* additional compression filters
* readers for GeoTIFF, GRIB2, CDF, FITS, PDS4, and now DICOM.
* netCDF example programs for the book: The NetCDF Developer's Handbook

In the 3.0 release I add a reader for DICOM, so that DICOM files appear as
netCDF files.

DICOM stands for "Digital Imaging and Communications in Medicine". It is
the universal international standard used across healthcare for storing,
transmitting, and managing medical images—such as MRIs, CT scans, and
X-rays.

The NEP DICOM reader means that DICOM files can be opened with netCDF
visualization and computational tools.

I hope researchers find the new capability helpful, and that the rich
eco-system of tools surrounding netCDF can shed some additional light for
medical researchers.

The NEP can be found here:

Keep on NetCDFing!
