        public static long incrementHeight​(long height)
        Increment the Stream Management height counter. Quoting XEP-198 4.: "In the unlikely case that the number of stanzas handled during a stream management session exceeds the number of digits that can be represented by the unsignedInt datatype as specified in XML Schema Part 2 [10] (i.e., 2^32), the value of 'h' SHALL be reset from 2^32-1 back to zero (rather than being incremented to 2^32)."
