Add Mabia (Gur) languages

https://www.imdb.com/title/tt4210112/

This movie produced in Ghana is in the language Kusaal, a Mabia (Gur) language. Please add Kusaal to your language list so the proper language can be assigned to this film.

You should also add "Mabia languages" (the more scholarly name) or "Gur languages" (the more colloquial name) to cover other films that use any of the 70 languages in that group, spoken in west Africa. Or maybe "Mabia (Gur) languages".
