feat(opinion_types): Add support for opinion types

Modeling the types we have in Courtlistener, we should
be able to add opinion types if not default Combined Opinions

This should allow us to caputre multiple opinion types
and let courtlistener group them together when it occurs in
the handful of courts we know about.
