dimension name should be lat_lon because lat comes before lon

[ahijevyc]

This came up when dealing with #1332.

The dimension lon_lat should be named lat_lon because latitude is in the zero-index and longitude is in the one-index.
This is analogous to how the min_max dimension contains the minimum value in the zero-index and maximum value in the one-index. You wouldn't want to have a dimension name like max_min because min comes first.

Overview

rename dimension lon_lat -> lat_lon because the latitude index comes before longitude.

After tracing the way bounds_array is constructed in _populate_face_bounds it is likely that latitude comes first and longitude comes second. That's why it should be renamed.

All the other variables with lat and lon in their names seems to be consistent with the order of lat and lon in their data.

Nice catch!
