Ed25519 documentation wrt separate PublicKey

[kevlar700]

The documentation only describes creating a fresh keypair and extracting the public key.

Is the way to utilise a separate public key from another language?

SimplePublicKey pubkey = SimplePublicKey(pkbytes, type: KeyPairType.ed25519):

Should this be added to the examples/documentation?
