Inconsistent implementations of eqBy, compareBy, eq, compare

[mlms13]

Option

• [x] eqBy
• [ ] eq (that accepts an Eq module argument)
• [ ] compareBy
• [ ] compare (that accepts an Ord module argument

Array

• [x] eqBy
• [x] eq
• [ ] compareBy
• [ ] compare

List

• [x] eqBy
• [x] eq
• [ ] compareBy
• [ ] compare
• [ ] Ord

It looks like we have compareBy for tuples and Relude.Map, but maybe not for anything else.
