addAdvancedMsgListener
Introduction
Add an advanced message listener, which can be used to listen for all the receiving messages.
The related callback functions can be defined in V2TimAdvancedMsgListener.
Invoking this method will add an additional new listener to the array of listeners.
It is suggested to register an advanced message listener, just after logging, to ensure all the messages can be received.
