Switch BNTX research

Nice work on the tool! I'm not sure if you've looked into BC4 textures yet, though i've taken a look at some BC4 textures myself and it seems that they're missing the green and blue channels.
Here is DK's texture in MK8D

Well, BC4 is just a greyscaled image anyway, so the green and blue would be identical to the red channel.

Btw did you have any luck figuring out how the swizzle works on non pow2 textures?

The way I've got it for my QuickBMS script right now is incredibly hacky and frankly I'm not even sure how it's working, so I can't say for sure.
