[Support #PRI-562474]: Gempak/ER40 reanalysis data?

Pete,
The ensemble extension comes from the gb/gbensemble.c routine. The ENHW is a
whole
ensemble weighted median.
The nagrib decoder provides a parameter PDSEXT that gives you the control to
turn off the
appending of extensions to the parameter names (such as the C001, P001, etc).
Beware, if you turn that off, you need to decode all ensemble members
into different files so that they don't overwrite each other (eg, when you have
HGHTC001, HGHTP001, HGHTN001, HGHTP002, etc., without the extension, they
will all be HGHT). The ens_ grid functions are designed to work that way with
separate files as well, so its not a bad thing, just more complicated in
determining the output file name.
For dcgrib2, I have the flag to add extensions hardcoded in
$NAWIPS/unidata/ldmbridge/dcgrib2/dcwppg.c
to "pdsextflag = TRUE;".
I could create a command line variable for dcgrib2 to toggle that as well.
