Toy Example

let code = Code::builder()
    .append(OpCode::PUSH1)  // OpCode
    .append("02")           // hex character

    .append(OpCode::ADD)
    .append(OpCode::PUSH1)
    .append("00")
    .append(OpCode::MSTORE)
    .append("60206000")     // hex string
    .append(OpCode::RETURN);
    .clone();
