KZG Rust

Rust port of https://github.com/ethereum/c-kzg-4844 . Uses the blst rust bindings for all BLS functionality.

Tries to be almost a line to line port of the C code in c_kzg_4844.c while rearranging some consts and utils into their own rust modules. Runs same test vectors from the original repository.

The crate exports 2 modules: kzg_mainnet and kzg_minimal which correspond to the mainnet and minimal spec variants in the ethereum consensus specs

Each module contains the following:

Following constants:

• FIELD_ELEMENTS_PER_BLOB
• BYTES_PER_BLOB

A Kzg struct with the associated methods:

• load_trusted_setup
• load_trusted_setup_file
• blob_to_kzg_commitment
• compute_kzg_proof
• compute_blob_kzg_proof
• verify_kzg_proof
• verify_blob_kzg_proof
• verify_blob_kzg_proof_batch

The following structs with specified values of the FIELD_ELEMENTS_PER_BLOB constant which refers to either mainnet or minimal spec parameters:

• Blob
• KzgSettings
• TrustedSetup

The TrustedSetup struct is provided as an additional helper struct in this library to parse trusted setups in the json format provided in the ethereum consensus specs
