* Compresson is improved for Level 9, at the cost of a little performance.
* Compression is improved for Level 3, by switching from deflate_fast to deflate_medium.
* Levels 3 and 4 have been reconfigured to provide a better gradual tradeoff for speed/compression between levels 2 and 5.
* Deflate_quick (Level 1) has been improved to default to a bigger windowsize and support changing the window size like the other levels.
* Deflate_rle has been optimized with its own compare_256 implementation.
