Update to distributive-0.6.1

0.6.1 [2019.09.06]
* Add a Distributive instance for WrappedMonad m.

0.6 [2018.07.02]
* Remove fmapCollect.
* Avoid incurring some dependencies when using recent GHCs.

0.5.3
* Support doctest-0.12

0.5.2
* Revamp Setup.hs to use cabal-doctest. This makes distributive build
  with Cabal-1.25, and makes the doctests work with cabal new-build
  and sandboxes.
* Fix bugs in Data.Distributive.Generic that cause generic
  Distributive instances not to work properly for datatypes with
  recursive types
* Add genericCollect to Data.Distributive.Generic, and switch the
  underlying machinery in that module to work on a collect-like method
  instead of a distribute-like one
* Add a test suite for regression-testing Data.Distributive.Generic

0.5.1
* Add Distributive instances for datatypes from Data.Semigroup and
  GHC.Generics
* Add MINIMAL pragma for Distributive

0.5.0.2
* A more elegant fix for builds on GHC 7.2

0.5.0.1
* Fix builds on GHC 7.2

0.5
* Added flags for removing some dependencies.
* Support doctests when building to non-standard locations (such as
  when using stack.)
* Support base-orphans
