We paired decaf with SHAKE, so must curve448 suite use shake too?

Based on RFC8032, this seems like a sensible change to make. Unless @kwantam has objections, I'll send a PR.

Wait, so just to make sure I'm understanding: deployed ed448 implementations use shake?

Yep, that’s my understanding, since SHAKE is required per the RFC (https://datatracker.ietf.org/doc/html/rfc8032#section-5.2).
