Can not load the HL1 mdl file.

It throw a exception "HL2 MDLs are not implemented " when I try to load a HL1 mdl file. I'm sure that the file is definitely a valid HL1 mdl and successfully load by the latest native assimp lib. So I replace the native dll on Assimp.NET by the newest one, it loads successfully, but failed on converting native scene to managed scene. In conclusion, the Assimp.NET's native lib is buggy, and if we want to use the latest native assimp lib, we need to update the managed wrapper too.

If you’re building from master and using the latest native version, you’ll have more luck building from this draft branch:

There were changes in native 5.1’s data structures which looks like is still in development, I usually only update once they tag a release.
