Expose internal module

I'd like to know the use case for the Internal module.

[expipiplus1]

Can't remember for sure now, probably to get access to the newtype constructors for deriving some instance

I second this, I can't derive complicated new instances of the Unboxable typeclass without getting access to Data.Vector.Unboxing.Internal, as methods like unboxingTo and unboxingFrom are internal.

For example, I can't derive Linear V2 without access to them it seems:

instance (Unboxable a) => Unboxable (X.V2 a) where
  type Rep (X.V2 a) = X.V2 (Rep a)

Perhaps they should just be made external instead?

Anyways, thanks so much for making this library! It saved me a headache.
