chore(aes): optimise circuits (#9) * Factor out byte XOR * WIP * include u8::max in the lookups generation (avoiding missing generators) * Complete optimisations * Add range checks --------- Co-authored-by: arnaucube <git@arnaucube.com>

Add poseidon encryption (rust native & plonky2 circuits) (#8) * implment poseidon-cipher https://drive.google.com/file/d/1EVrP3DzoGbmzkRmYnyEDcIQcXVU7GlOd/view natively * implement plonky2 circuit for poseidon-cipher * aes: circuit_gcm.rs group new_targets & build_circuit into just build for easier usage * Modify decryption and state hash * adapt circuit to new hash_state logic * extend nonce from F to [F;2] (<2^128) * two128 constant * replace old nonce & L approach by [n[0], n[1], L, 0, 0] to bind nonce&L into the initial state --------- Co-authored-by: Ahmad <root@ahmadafuni.com>
