Use pycountry instead of iso-639 for languages

Browse Source 
The latter is a fork that hasn't been updated since 2016 and the
original still seems to be well maintained, with recent database

Also, pycountry supports ISO 3166-2 (administrative zones), which
we could eventually use for sub regions.
