JPakeRound1Payload
The payload sent/received during the first round of a J-PAKE exchange.
Each JPAKEParticipant creates and sends an instance of this payload to
the other. The payload to send should be created via
JPAKEParticipant.CreateRound1PayloadToSend().
Each participant must also validate the payload received from the other.
The received payload should be validated via
JPAKEParticipant.ValidateRound1PayloadReceived(JPakeRound1Payload).
