Derive the account address that a post-quantum signature authorizes.
Unlike an Ed25519 signature, a PQ signature carries the scheme, salt and
public key of the signing account, so the address it authorizes is fully
determined by the signature and does not have to be supplied out of band.
This also validates the signature's self-consistency: the salt must be the
canonical one for the given scheme and public key, which is what the network
requires.
