Gribmap in GrADS 2: index file not portable to other endianess

[Jennifer Adams]

The index files should be usable on both big and little endian
machines. I will look into why this feature is no longer working in
version 2.0. N.B. GrADS 1.9 cannot handle index files created with
the gribmap in GrADS 2.0.
