I'm starting to track outside work for opaque-ke here so you can take a look and chime in @kevinlewi.

Almost there, missing the update to digest 0.10 and the implementation in p256 to go live.

I made the PR's in advance to update p256 & all it's dependencies to digest 0.10. In the meantime we can already rely on them to test our implementation.

This is done and all crates related to us are released now.
