Is there something we require or can we just use the latest bonsai-sdk release?

I've implemented that at the requirements later

Allows for requesting and proving of Blake3 Groth16.
Under the current Groth16 compression, there are 5 public outputs which when SHA2 hashed gives the claim digest.
This new compression type introduces a new claim digest, which is the BLAKE3 hash instead.
This new claim_digest cannot be calculated on-chain, which means that proof requests for this BLAKE3 hash cannot be fulfilled with (image_id, journal). What this means is requests with Blake3 compression need to use the ClaimDigestMatch predicate.
NOTE: This compression only works for guest programs what have journal size of 32 bytes.
Example of usage here: https://github.com/ec2/boundless_blake3_example
This project currently forks 2 repos:
risc0: https://github.com/boundless-xyz/risc0/tree/ec2/v3.0.3-backport-3370
risc0-ethereum: https://github.com/ec2/risc0-ethereum/tree/ec2/bitvm2-release-3.0.1
TODO:
[] Clean up changes made to risc0-ethereum
[x] Rename shrink_bitvm2 -> blake3 groth16 everywhere
