DFinsupp.equivProdDFinsupp

{ι : Type u} →
  {α : Option ι → Type v} →
    [inst : (i : Option ι) → Zero (α i)] → (Π₀ (i : Option ι), α i) ≃ α none × Π₀ (i : ι), α (some i)

Bijection obtained by separating the term of index none of a dfinsupp over Option ι. This is the dfinsupp version of Equiv.piOptionEquivProd.
