Support multiple actions in one request

**Is your feature request related to a problem? Please describe.**
The internal Sagemcom API supports passing multiple actions in one request, which could speed up the request.

**Describe the solution you'd like**
Support passing multiple actions, perhaps by chaining the normal requests with a special parameter.

**Additional context**
How to handle exceptions? It is possible to have an error (exception) for one action, where others will succeed without errors.

How to have typed responses? This is currently a major advantage of this client.

该 issue 未指定任何文件、测试或入口点，因此请先定位现有的 request 和类型化响应处理逻辑。在实现之前，确定如何表示多个操作、如何报告部分异常，以及如何继续支持类型化响应；完成要求是形成一致认可的设计并具备相应的覆盖率。
