LZSA compressor

A new compressor. Does not seem bad at all!
And there is a Z80 decompressor as well...

It seems to be a very good alternative to MegaLZ, ZX7 or LZ4. Aplib, Exomizer and Shrinkler are still useful for big compression rate. Since the decrunch is fast, it could also be a good alternative to CPC_T and other native CPC crunchers. We've to make some tests!

Does someone did some tests ?

I will do so soon and report back.

I tested lzsa with my WIP project for Revision.
Source file is 11494 bytes, Shrinkler crunched it to 3388 bytes (which is impressive), lzsa yielded 5253. Too big for 4k :(

What's wrong with 3388 bytes?

I think that "too big" was refering to the LZSA's 5253 bytes :)

Don't forget 128 bytes header + 200 bytes decruncher!

Bad use of interpunction by me. Yes, I was referring to lzsa's result. Shrinkler is doing great. Also thanks for hinting at the header - wasn't aware of that!
