A fresh PrivateKeys/PublicKeys pair: a signing key and an
encapsulation key in the chosen schemes (keypair_opt, or
keypair_opt_using with rng). The signing pair is made first, then the
encapsulation pair, drawing from rng in that order; a post-quantum
scheme with rng throws General at its turn, as the reference does.
