Support post-quantum signing algorithms

[mooreds]

I'm not aware of any production grade implementations of the NIST ones: https://www.nist.gov/news-events/news/2024/08/nist-releases-first-3-finalized-post-quantum-encryption-standards

So it'd be awesome to implement at least one. The research I've done mentions that Dilithium is the easiest to code from scratch: https://pq-crystals.org/dilithium/
