[netCDFDecoders #UKB-233671]: problem decoding grib2 2.5 grad

Olivier,

If you give me the location of the ftp and the name of the file, i
can download it and test it on the new code. there are several
braches in the code that i don't have test grib2 files for so 
your files are important.

thanks,
Robb...
