Solve SEGV in mutool clean with fuzzed file.
While attempting to debug a valgrind issue with:
013b2dcbd0207501e922910ac335eb59_asan_heap-oob_a59696_5952_500.pdf
I found that mutool -difggg on it failed with a SEGV. This is due to
us parsing an array with a large invalid indirection in it (e.g.
[123456789 0 R]) and then the renumbering code assuming this is valid
and accessing off the end of an array.
