Feature: Allow using `orderBy` in queried nested relations

Currently you can only sort at the top level. It would be nice if any nested relationship queries would also support the orderBy parameters.

Having take, where, skip, could also be useful I think, especially for filtering within nested relations

I'm going to be looking into this soon as I have a few use cases for it.
