Alternative multirec instances deriver

New features/changes:

  • Works with arbitrary monomorphic types, e.g. ([Int],String), not just names that refer to monomorphic types.

  • The names of the "proofs" (= constructors of the family GADT) are now specified by the user. In other words, a proof now doesn't need to have the same name as the type whose family-membership it proves anymore. This is useful if you're working with existing code where the type's name is already taken on the value level.

  • The names of the constructor-representing empty types are also customizable now.

  • The type sums in the pattern functor are now balanced trees of (:+:) rather than right-nested lists. This cuts down the size of the value-level code (and hopefully helps with compilation time).
