Omission / oversight: No ability to decompress meshes for cli tools.

[JernejL]

Compressonatorcli can decompress images, but it cannot seem to be able to decompress compressed models.

I tried various examples of "compressonatorcli.exe -meshopt -decomp" and "compressonatorcli.exe -decomp" on draco compressed glb files and all it does is say "No files to process in source dir" or "Invalid Command".
