[Possible bug] sha256 block type elements comparison uses vector comparison

[CblPOK-git]

` #include <nil/crypto3/hash/algorithm/hash.hpp> #include <nil/crypto3/hash/sha2.hpp>

using namespace nil::crypto3;

[[circuit]] bool sha256_example(typename hashes::sha2<256>::block_type block0,
                                                              typename hashes::sha2<256>::block_type block1) {

    return block0[0] < block1[0];

}`

quick fix: replace O1 with O0 in the CircuitCompile.cmake
