PhysX requires all of its actors to have cooked mesh data. This cooked
data is unfortunately not compatible with other versions of PhysX outside
of the minor branch. The format is also largely unknown. Therefore, it is
relevant to allow CWE prps to include an engine agnostic physical format
to reduce our dependencies on proprietary libraries.
All PhysX blobs thankfully begin with the magic string NXS\x01, so we now
abuse that by adding our own format that begins with the magic string
HSP\x01. These blobs are cooked on the fly while already cooked blobs are
passed directly on to PhysX.
