plzip_modded - parallel 64bit lzma (de)compressor and a direct 4x4:lzma replacement

[elit]

Btw Razor CAN be multithreaded but externally, plzip could invoke (de)compress copy of RZ function for each block processed(probably spawn new instance for each), this can be also done with 4x4 btw I just dont know if it work without stdio.
