Add More Hashing Benchmarks

[mariari]

Currently I've added a Blake2 benchmark for risc0, but it would be nice to get a good basis of hash functions bench marked:

Known hashing functions to benchmark and compare

• Blake 3: Miden
• Sha 256: Miden
  • https://github.com/maticnetwork/miden/blob/main/assembly/benches/program_compilation.rs
• Blake3: Risc0

It would be great to get contributions for all ZKVM machines. Ideally we can get all the machines to have the same algorithm, so we can compare speeds more easily.

I should also verify the answer somehow.

For the Blake 3: Miden example I take it on faith value that I'm feeding the inputs correct and getting the correct output
