In preparation for the potential Taproot soft fork, libconsensus should be updated to support verifying Taproot scripts.

There are two changes I see as necessary:

- Add a VERIFY_TAPROOT flag
- Change the API to support passing in spent outputs (bitcoinconsensus_verify_script_with_spent_outputs?)

    std::vector<unsigned char> data = ParseHex(str);
    return CScript(data.begin(), data.end());
}
BOOST_AUTO_TEST_CASE(script_FindAndDelete)
