Instance methods too strict

These instance methods look too strict.

@sjoerdvisscher Any thoughts?

Tbh I never give strictness much thought until something breaks. Other instances for Procompose and Pair in profunctor/bifunctor don't seem to need anything special either, so why do these?

Fair enough. Let's leave that until we see a problem.
