Python implementation

Will there ever be a python implementation of a streaming example? It's not obvious how other clients that don't have native http/2 support will be able to use aws-transcribe-streaming. Open to hearing other ideas. Obviously one could set up a pipe or websocket to the java implementation, but would love other thoughts

未指定任何文件、测试或入口点。首先查看现有的 Java AWS Transcribe 流式示例，以及 issue 中关于不支持原生 HTTP/2 的 Python 客户端的问题；只有在达成一致的实现方案并明确定义支持标准后，才算完成。
