Ability to override Uint8Array with a inherited type e.g. Buffer

[Borewit]

This offers better backwards compatibility then v0.2.0 allowing by specifying Buffer for Array,, e.g.: IGetToken<T, Buffer>

Ability to override Uint8Array

Smart!
Another method if they don't want to do that could be to just extend (monky patch) something

class Backward extend A {
  getSomethign(...args) {
    return Buffer.from(super.getSomethign(...args).buffer)
  }
}
