i determined that the small size difference mentioned previously seems
to actually have been a small bug in the original, which got
"accidentally" fixed. that said, i think this faster version is ready

massive LZ search optimization (needs tweaking)

output is now a couple of bytes larger sometimes for some reason but
seems to decompress fine, and the compression is 3-4x faster which is
great
