RealtimeClientEventConversationItemCreate interface

Add a new Item to the Conversation's context, including messages, function calls, and function call responses. This event can be used both to populate a "history" of the conversation and to add new items mid-stream, but has the current limitation that it cannot populate assistant audio messages. If successful, the server will respond with a conversation.item.created event, otherwise an error event will be sent.
