Title: Loosen restriction on mtl to 1.1.

I don't know if this is a concern at this point, but digestive-functors works just fine with mtl-1.1, which I'm using in this project. I can maintain a separate ‘me’ branch for this if it's a bother to have this version without the instances that mtl2 added.
