* feat: change bytecode hash function from Keccak to Poseidon * fix TestStateProcessorErrors * rename files * copy iden3's poseidon package to local * update poseidon hash * apply new hash in codehash * extend hash method, use actual code size as cap * prune keccak(nil) for empty code * update empty code hash references to Poseidon * add TestPoseidonCodeHash * use keccak for empty code hash * go mod tidy * goimports * use Poseidon code hash in state and sync tests * run goimports * run goimports * remove unnecessary reallocation from CodeHash * goimports * move codehash API to separate module * add missing package * fix review comments * improve comments Co-authored-by: Ho Vei <noelwei@gmail.com>
