ControlNotificationExtendedOutput identifies the %extended-output notification, available since tmux 3.2a. Its wire grammar is %extended-output <pane ID> <age> { zero or more <reserved argument> } : <data>. ParseControlNotification returns its arguments as the prefix arguments, then zero or more reserved arguments, then the data tail; the prefix arguments are pane ID, age. Its tail may be empty.
