Resolves #394

Generates a couple of warnings with hashable-1.4, because Eq is now a superclass of Hashable:

src/Relude/Nub.hs:115:1: warning: [-Wredundant-constraints]
    • Redundant constraint: Eq a
    • In the type signature for:
           hashNub :: forall a. (Eq a, Hashable a) => [a] -> [a]
    |
115 | hashNub :: forall a . (Eq a, Hashable a) => [a] -> [a]
    | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

src/Relude/Nub.hs:142:1: warning: [-Wredundant-constraints]
    • Redundant constraint: Eq a
    • In the type signature for:
           unstableNub :: forall a. (Eq a, Hashable a) => [a] -> [a]
    |
142 | unstableNub :: (Eq a, Hashable a) => [a] -> [a]
    | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

I can fix the type signatures with CPP if you like.
