The Gorilla and Dictionary compressors crashed on malformed data with the reverse decompression iterator and the bulk decompressor. This issue was reported by Mehmet Ince @mdisec https://mehmetince.net/, and the test case binaries are his contribution that I integrated into the fuzzer test suite. This change adds validation for these cases and adds reverse iterator coverage to the fuzzer tests, so the randomised test will catch future issues. It already caught issues in other compressors like deltadelta, which I also fixed in this review.
