Closes fizyk20#110
Adds an analogue of the `[expr; LENGTH]` array initialiser to the `arr!` macro, i.e. `arr![Type; expr; LENGTH]`. Can be used in const contexts. Note that this implementation builds upon fizyk20#129, which should be reviewed/merged before this.

Introduces a trait defining an associated constant of the `Self` type. The trait is parameterised to distinguish arbitrary constants. An implementation is provided for `GenericArray`, providing means of constructing arbitrary `GenericArray`s in const context. This plugs a gap that exists even if fizyk20#130 is 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).

Introduces 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 if fizyk20#130 is 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).

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).
