std::vector<Signal> m_signals; 中的sigs没有按照 startbit 排序

它的麻烦之处体现在 parser.parse_message(id, data, result_values); 的 result_values ，也没有按照sig排序，需要 打印 结构体 来得到信号的名称

    std::vector<double> result_values;

    parser.parse_message(id, data, result_values);

    if (id == 0x18ff52f0) {
        value1 = foloat2string(result_values[5]);
        value2 = foloat2string(result_values[3]);
        value3 = foloat2string(result_values[0]);
        // float 转 string

    } else if (id == 0x18ff5678) {
        value4 = foloat2string(result_values[2]);
        value5 = foloat2string(result_values[0]);
    }
