[netCDFDecoders #SDJ-821116]: GRIB constant-valued grids problem and fix

Robert,

I changed the Grib1 indexing to have offsets of the GDS and the data, this 
should solve your noted problems. The Grib package went under a major refactor 
the last months, the release should be out sometime this week.
