OPENDAP/bes: Version 3.20.7 for Hyrax 1.16.2

Hyrax can generate signed S3 requests when processing dmr++ files whose data content live in S3 when the correct credentials are provided (injected) into the server. For configurations that require Hyrax to authenticate to access various remote resources, Hyrax can now utilize ~/.netrc (or a netrc file may be specified in site.conf) and Hyrax will use the appropriate credentials, if they are present. The get_dmrpp script for dmr++ production has been enhanced with better configuration options and built in QC tests for inventory along with a simple value test. The get_dmrpp script will default to using a template string for the value of the dmrpp:href URL when a URL is not provided with a -u switch. This allows the URL to be injected later. We fixed a problem with fill values by converting the FillValue type to the data type of the associated variable. Fileout NetCDF has a new configuration key, FONc.NoGlobalAttrs that can be used to suppress global attributes. hdf5_handler The CF option support is enhanced. Added support for correctly generating dmr++ files. Enhanced support to handle netCDF-4 like HDF5 files and general two dimensional latitude and longitude files.
