Description

These are defined in sections 6.22 and 6.23 of the Challenge Protocol Specification. Implementing support for them in the PA-RoT server is pending on #43, but implementing the message parsing itself can be done before that.

Since we would be implementing these on top of the FPM, it's unclear if we want to re-use the Cerberus message type bytes for these, or use our own until we reconcile the PFM and our FPM. We implement the PFM now, so this bit is irrelevant. =)
