x2 anime model?

[cyaoeu]

The quality is great but the 4x anime model in a lot of cases creates huge resolution files. A x2 anime model could be useful if you don't want to further process (resize) the images after the initial output. If it's not a lot of work such a model would be appreciated.

We will add it.

For now, you can use another argument --outscale. For example, you can add --outscale 2 to upsample x2.

In the vulkan.exe version there's the -s parameter, however the output does not seem quite right:
#247

any quick fix for it or something inside the code?
