Sending a streaming response message

Feature Overview
Send streaming response messages to the robot via this API.
For a complete text, you may need to call this API multiple times to output the parts sequentially to the client.
On the first call to this API, the backend generates a MsgKey to represent the message this time. Subsequent calls require transmitting the MsgKey as parameter to the IM server.
If the App uses TUIKit version 7.7.5282 or higher, it can automatically display streaming output message effect.
If the App does not use TUIKit, it needs to manually display the streaming output effect according to the streaming text output protocol.
