Like glib.sequence.Sequence.lookup, but uses a #GSequenceIterCompareFunc
instead of a #GCompareDataFunc as the compare function.
iter_cmp is called with two iterators pointing into seq.
It should return 0 if the iterators are equal, a negative value
if the first iterator comes before the second, and a positive
value if the second iterator comes before the first.
This function will fail if the data contained in the sequence is
unsorted.
