Add the Compactable construct to dhall-bhat.

Class Functions:

  • compact : (f : Functor) -> f (Maybe a) -> f a
  • separate : (f : Functor) -> f (Either l r) -> (f l, f r)

Instances may be automatically derivable from the above two functions.

Combinator Functions:

  • mapMaybe
  • mapEither
  • filter
  • partition
  • apMaybe
  • apEither
  • bindMaybe
  • bindEither
  • traverseMaybe
  • traverseEither

EDIT: Not sure if filter or partition are useful
