Adapt import_zip script to use the right subdivision type per country
Now that we limit the type of subdivisions per country in addresses \[1\]\, we should adapt the country import\_zip\.py script to honour the same criteria\. \

\
Maybe we should just always use the smaller \(more precise\) subdivision\. \
