Added household data for districts with no information
Did a few things in this MR:
- Imported the dwelling numbers to calculate household data for wooden and non-wooden from the dwelling numbers list created in the previous MR instead of the earlier from the database.
- Added functionality to calculate household data for districts with no information and add them to the database.
