 Special thanks go to Cholok for providing me references to many of the XPK-compressors.
 
+Thanks to nocash for ByteKiller format and variants reverse engineering

 BZIP2 tables for randomization have been included, they have BZIP2-license.
 
 SASC/SHSC decompressors have been re-implemented by using the original HA code from Harri Hirvola as reference. (No code re-used)
