WtBtRunner是回测的主程序，启动改程序时，会进行配置文件和dll的加载

1. 解析参数，由cppcli::Option完成参数解析
2. 初始化日志打印

   	std::string filename;if (lParam->exists())filename = lParam->get<std::string>();elsefilename = "./logcfgdt.yaml";WTSLogger::init(filename.c_str());

3. 解析配置文件

   	if (cParam->exists())filename = cParam->get<std::string>();elsefilename = "./configbt.yaml";if (!StdFile::exists(filename.c_str())){fmt::print("confiture {} not exists", filename);return 0;}WTSVariant* cfg = WTSCfgLoader::load_from_file(filename.c_str());

4. 初始化HisDataReplayer
5. 根据配置初始化各种策略的mocker
6. 准备就绪，开始运行

   	replayer.prepare();replayer.run(true);
