xpkLZ40.library is an XPK packer based on lz4.library (the extra "0"
is just to pad out the ID to the required four characters).

LZ4 is an extremely fast LZ77-style packer with reasonable compression.
This library should be used when packing pseed is more important than
compression ratio.

Example benchmarks against some other popular OS4 native sub-libs:
File 'NetSurf' with a size of 14753427 bytes.
