AUGEOSFV-14, while testing more files and find the tool doesn't support the use of datafield for grid lat and lon. Ideally lat/lon should be calculated via HDF-EOS5 APIs, however, some NASA HDF-EOS5 products don't give the correct project parameters. Instead they provide correct lat/lon fields. So I enhance the tool by providing an option for users to use data fields for lat/lon. Also two helper fucntions check_attribute_existence and delete_attribute are added. Tested with a fake grid file. ncdump gives the correct output.
