Add population data missing for locality in Province 7

[cliftonmcintosh]

Our data set for population is missing data for one locality in Province 7. The data are available in our "Federal Data" in https://github.com/Code4Nepal/data/.

Add the data to the population.sql file. Please put the data in a logical place -- so that all data for the same district are in rows next to each other. That will make it easier to review in the future.

• When you add them, you will add one row for female population and another row for male population. See the current file for examples.
• You will need to update the totals for the district for that locality to include these additional data.
• You will need to update the totals for Province 7 to include these additional data.
• You will need to update the totals for Nepal to include these additional data.

Here are the localities whose data are currently missing.

geo_level	geo_code	name	parent_name	parent_level	parent_code

• "Dhangadhi" in "Kailali" is "Dhangadhi Sub-Metropolitian City" in the federal population data: https://github.com/Code4Nepal/data/blob/master/Federal%20Data/753%20Local%20Unit%20Population%20and%20HouseHold/PRADESH%207/Kailali/Dhangadhi%20Sub-Metropolitian%20City.csv
