Request: Support creating VTFs from DDS textures

[WinterPhoenix]

DDS is a texture format used by several games that's similar to VTF. For example, some textures in CS:GO and CS: Nexon are DDS instead of VTF/VTEX/etc.

Currently

In CLI, MareTF will say it successfully TF'ed the image, but the output VTF is corrupt, seemingly with any given options.
