Merged requested to merge feature/household_data_expand_construction_material into refactoring_to_sql
Calculated the household numbers and household members for construction material (wooden, wooden (excluding wooden and fire-proofed), wooden and fire-proofed and non-wooden) by multiplying the
total value of household numbers and household members to the proportion of dwelling numbers for each construction material to the
total dwelling numbers.
And inserted these values back into the household data (inserted only the values for construction material != 0 i.e. total).
