[TH] WI data cleanup

1. WI doesn’t need county level data
2. The data set we use stripped out identifiers
   like “Rm”, “Suite”, etc. We’ve added back in a
   “#” so that the number value isn’t just hanging
   off the end of the street address confusingly
3. The data set had “XXX PO BOX”, we reversed it
4. Ignore non CITY, TOWN, VILLAGE rows, including
   the STATE level row and the RETIRED rows
