All textures are currently saved as Unsigned (DXGI_FORMAT_BC*_UNORM)

Hi

First off, thank you so much this tool, it is superb!

Currently all compressed textures are saved out, at least as far as I can tell, as unsigned textures (DXGI_FORMAT_BC*_UNORM). However for things like normal maps it would be good to have an option to save them out as a signed (SNORM) texture as it requires less processing in the pixel shader.

Could this be easily added?

EDIT NB I cant add labels as requested as I am not a contributor

I have created a pull request that simply splits BC5 into BC5_U and BC5_S;
