* Run more decompression variants * Round trip the compression fuzzer and do partial decompression as well * Add a compression fuzzer that compresses into a smaller output buffer and test the destSize variant These fuzzers caught 2 bugs that were fixed in the previous commit. * Input buffer over-read in partial decompress * Partial decompress fails if output size is 0
