BoundedEnum instance for Int has invalid cardinality

[matthewleon]

Yes, Int violates a lot of typeclass laws... But the BoundedEnum instance having a cardinality of -1 seems particularly egregious. It certainly trapped me. Is this instance worth keeping despite that?

@paf31 what do you think we should do here? I guess we should use a Nat for cardinality really...

We could drop the instance, or use Number instead of Int perhaps? 😕

[paf31]

I think we should just remove it for now.
