[Deflate] Replace crc32 of a match with bytes contacenated into UInt32
...
Previously, we were using crc32 to identify matches when doing compression. This not only was an overkill computationally (the new version has boosted the compression speed), but it could also lead to incorrect results in some rare cases (potentially, only theoretical situtations) due to collisions of crc32 algorithm.
