RustCrypto: Hybrid Const Generic / Typenum Arrays

Hybrid array type combining const generics with the expressiveness of typenum-based constraints, providing an alternative to generic-array and a incremental transition path to const generics.

About

This crate uses typenum to enable the following features which aren't yet possible with the stable implementation of const generics:

• #60551: Associated constants in traits can not be used in const generics
• #76560: Complex generic constants: feature(generic_const_exprs)

Internally the crate is built on const generics and provides traits which make it possible to convert between const generic types and typenum types.
