* \brief Handshake implementation of the Noise "XXfallback" pattern.
*
* The "XXfallback" pattern provides mutual authentication of the two
* communicating parties after a previous "IK" handshake has failed.
* The application should use startFallback() instead of start() to
* start the new handshake.
*
* This class provides the core "XXfallback" functionality. Subclasses provide
* implementations of "XXfallback" that use specific algorithms, such as
* Noise_XXfallback_25519_ChaChaPoly_BLAKE2s.
