Investigate equivalent dependency libraries from the starkware C++ implementation

[thor314]

See list here: https://github.com/starkware-libs/stone-prover/tree/main/src/third_party

Particularly it would be nice to evaluate relevant comparable libraries to

• [ ] XKCP
• [ ] Blake2
• [ ] gsl
• [ ] jsoncpp

[agnxsh]

https://crates.io/crates/serde_json for jsoncpp, i believe this should suffice, also earlier I had linked the crate for blake2 here's a good video to understand how blake2 works (a good video for beginners maybe(?)) https://www.youtube.com/watch?v=icEnsXiO378

serde_json probably best ye, and cool I haven't looked at BLAKE2's design, maybe link to it in a doc comment or a README page about tools we're using where relevant
