Add NIF to use KZG functions

[mpaulucci]

See the Ethereum C implementation here: https://github.com/ethereum/c-kzg-4844/tree/main

We could either use the Rust bindings https://github.com/ethereum/c-kzg-4844/blob/main/bindings/rust/README.md with rustler or the C implementation.

The goal is to be able to make these tests pass: https://github.com/ethereum/consensus-specs/tree/dev/tests/formats/kzg

Functions to implement:

• blob_to_kzg_commitment
• compute_kzg_proof
• compute_blob_kzg_proof
• verify_blob_kzg_proof
• verify_blob_kzg_proof_batch

It might make sense to divide this ticket into one per function. Keeping it like this for now, but feel free to change it.
