1. Further expand array size support …

   This adds support for sizes identified as needed for post-quantum
   KEM/DSA use cases, namely the ones from this comment:
   
   RustCrypto/KEMs#2 (comment)
   
   These should ideally get expanded into some consistent multiples above
   1024, e.g. multiples of 32, and generated in a purely automated manner
   (e.g. by a script that can break down the bit representation and build
   the generic syntax), but this should at least be sufficient to unblock
   these use cases.
   
   Note that `UInt<UInt<..<UTerm, B#>, B#...` aliases expressing the
   explicit bits for a given number are used instead of e.g.
   `<U1024 as Add<U32>>::Output` because when the latter is used it causes
   similar errors for conflicting trait impls as we saw with
   `typenum::U<N>` for whatever reason:
   
       error[E0119]: conflicting implementations of trait `traits::ArraySize` for type `UTerm`
          --> src/sizes.rs:82:13

           |               first implementation here
