Really good compression rate. But slow to depack. For my eyes the exomizer looks best.

Yes, the main problem is the multiplication to get the next bit. But even on Jaguar with single cycle multiplication it is very slow.

This and the large depack routine.

I need to test also depacking from ROM. But I guess LZ4 will outperform every other packer unless the pack ratio is the goal.

That is why I used it in Bad Apple for video packing . That and because I could used stream depacking.

My problem with exomizer, the "Level" compression seems to be size limited. I wanted to pack the Jaguar image (128,000 bytes) and it just does nothing.

And the "raw" compressed format seems to be different from the "level" format.

(Besides: I could not find any documentation explaining the differences between raw and level).

Added a `Exomizer RAW` mode unpacker. No special handling of input data (adding additional bytes) needed. Slightly quicker than "krilldecr"
