Response
ProcessorInstance.Response.Handled if processorInstance acknowledged and processed the message,
ProcessorInstance.Response.Unhandled if not or ignored.
Send a message with a piece of data to be immediately evaluated by the ProcessorInstance.IRealtime.OnMessage on the real-time side.
This is the real-time counterpart of ControlContext.SendMessage: it dispatches synchronously to the
processorInstance's IRealtime implementation from within this
RealtimeContext.
The message is passed by reference, so the processorInstance can modify it.
