2024-02-04	Add json fuzzer with seed files from #1123 and test suite	Jay Berkenbilt
	...as well as some cases generated in CI from earlier attempts at fixing this.
2024-01-17	Fix incorrect handling of invalid negative object ids	m-holger
	Fix two errors introduced in #1110 and #1112. Since #1110, encountering the invalid indirect reference #1110 -2147483648 n R produces an integer underflow which, if undetected, immediately trigger a logic error. Since #1112, object -1 0 R may be incorrectly identified as an earlier generation of itself and deleted, invalidating a live iterator.
