We add more tests showing functors and now bifunctors are definitionally involutive. We also show that opposite natural transformations do not have this behaviour since the proof of naturality is inverted. I think it might be time to consider adding redundant information to
Is1Naturalso that we also keep the inverted naturality around like we did forcat_assoc_opp.
