Handling of currently unsupported files

HKX is able to be dealt with, although the method to do so currently is a bit finicky:

• find an oldrim version of the mod you are converting, unpack it all, and pass it as a second parameter to the CONVERT_MOD script.
• It will search for matching hkx files, and copy the oldrim versions to the working directory if it finds them
• Finally, the script will use HavokBehaviourPostProcess.exe to convert them to PS4 format (which the NX uses)

This is LessThanIdeal™

It could be expanded to automatically unpack the oldrim mod (chances are the hkx are in a bsa file), and even unpack the zip of the oldrim mod if one is provided instead of the folder.
It's also a problem that it requires HavokBehaviourPostProcess.exe. I only just got rid of the Archive.exe dependency from the Creation Kit. Now we need another tool, and even if it exists in the Havok SDK tools somewhere, that is no longer publicly available, either.
