FFunctor typeclass

Micro library with a Higher Kinded Functor in the spirit of HFunctor, MFunctor and MonadTrans (which all have different kindedness).

Useful to map over the type parameter in a record of functions, e.g. https://www.benjamin.pizza/posts/2017-12-15-functor-functors.html and https://discourse.haskell.org/t/local-capabilities-with-mtl/231 and https://discourse.haskell.org/t/some-limits-of-mtl-with-records-of-functions/576
