- **Key pair generation**
  - Overhauled, but supported APIs unchanged

This PR adds a lot of new individual functionality. But most importantly
because
of the new key material representation, it is now trivial to add new
algorithms
(as shown by this PR).

Now, when adding a new algorithm, it is also widely supported - for
example
previously we supported ED25519 key pair generation, but we could not
import,
export, sign or verify with ED25519. We can now do all of those things.
