Various compression/decompression functions. The LZ-type algorith (LZRW1/KH) was originally written by Kurt Haenen <ghgaea8@blekul11> and made portable by P. Hintjens. This is a reasonable LZ/RLE algorithm, very fast, but about 30% less efficient than a ZIP-type algorithm in terms of space. The RLE algorithms are better suited to compressing sparse data. The nulls variant is specifically tuned to data that consists mostly of binary zeroes. The bits variant is tuned for compressing sparse bitmaps.
