[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.

[LZ4] Fix incorrect usage of dictionaries in compression
...
Previously, the dictionary was effectively ignored, since it was never used to populate the table of matches. Additionally, we fixed another issue with dictionaries, which was hidden, because we never really used them.
