Inaccurate total population of 51 million

[cliftonmcintosh]

The total population listed for Nepal using our current data set is 51 million. That seems very inaccurate!

Googling shows estimates between 26 and 30 million.

See https://beta.nepalmap.org/profiles/country-NP-nepal/

The inaccurate data are here: https://github.com/Code4Nepal/nepalmap_federal/blob/dev/sql/population.sql#L1750-L1751
