Perhaps, for maximum interop, this should use https://crates.io/crates/const-default ? |

Utilises the `const-default` crate (behind a feature gate) to introduce a trait defining an associated constant of the `Self` type. An implementation is provided for `GenericArray`, providing means of constructing default `GenericArray`s in const context. This plugs a gap that exists even after fizyk20#130 was merged, as generic type parameters cannot currently be referenced in const context (e.g. if the repetition length provided to the `arr!` macro comes from a type parameter).
