Interface LiveClientRealtimeInput

User input that is sent in real time.

This is different from ClientContentUpdate in a few ways:

• Can be sent continuously without interruption to model generation.
• If there is a need to mix data interleaved across the ClientContentUpdate and the RealtimeUpdate, server attempts to optimize for best response, but there are no guarantees.
• End of turn is not explicitly specified, but is rather derived from user activity (for example, end of speech).
• Even before the end of turn, the data is processed incrementally to optimize for a fast start of the response from the model.
• Is always assumed to be the user's input (cannot be used to populate conversation history).
