harp_import_test_fuzzer: ASSERT: (char *)gs.pos < (char *)gs.end #218

Not sure if this is something that harp can catch or it has to be solved in netcdf. It's way too short to be a valid netcdf file for harp processing at 8 bytes long.

This is something that should be resolved in the netcdf library itself.
