load_processing_set does not load weather_xds

When the weather_xds was introduced, it was not properly added to the load_processing_set() function. This should be simple to fix:

     return ms_xds

read_processing_set() seems to load weather correctly.

This is no longer an issue, as it is now fixed in read_processing_set.py:_read_sub_xds().
