        POST /series/:id/unpublish/
        Unpublishes a repeating event series and all of its occurrences that are not already completed, canceled, or deleted. In
        order for a free series to be unpublished, it must not have any pending or completed orders for any dates, even past
        dates. In order for a paid series to be unpublished, it must not have any pending or completed orders for any dates,
        except that completed orders for past dates that have been completed and paid out do not prevent an unpublish. Returns
        a boolean indicating success or failure of the unpublish.
