[mikelodder7]

This adds

• Compatibility with liboqs 0.11.0
• Adds Debug to all structs
• FromStr for kem::Algorithm and sig::Algorithm
• Serialize/Deserialize use constant time serialization and hex when human readable, binary otherwise
• Exposes ML-KEM, ML-DSA, Cross, and Mayo
• Adds cargo careful to CI

I think some of this is obsolete due to #272. Is there any desire to redo the remaining additions?

[SWilson4]

Maybe @jmayclin would be interested in adding some of the Rusty features from this PR.

I'll close out this PR and base it off the new updates from #272
