Frequency distribution calculations for household data
The frequency distribution code is the last in data manipulation and would be added in 3 parts. the first part here: https://git.gfz-potsdam.de/dynamicexposure/globaldynamicexposure/exposure-japan/-/merge_requests/17 and second part: https://git.gfz-potsdam.de/dynamicexposure/globaldynamicexposure/exposure-japan/-/merge_requests/18 is already merged. In this last part, using the frequency distribution calculations, the error for mismatch of numbers is fixed for household and household member numbers.
