Simplify NetflixSession.parse_genres_for_video().

This method resolves genre references (IDs) to genre names.
Before this change, we would iterate the list of genre (names)
and then iterate the list of genre IDs to look for matches.
The same result can be established more efficiently by iterating
the genre references followed by lookups for their associated names.

Error handling for lookup failures has been left intact from the
original implementation.
