Shouldn't MatchGeneratorDriver be public?

I'm trying to write a streaming encoder, and since this type is not public, I'm struggling to embed it into my struct and such, since I cannot name this type.

Oh right! I think I will add a type alias that allows naming the "default" FrameEncoder. I don't think I want to expose the MatchGeneratorDriver. Having that type linked that explicitly to the new function probably was a mistake to begin with.
