Add "8x_NMKD-Typescale model" (best to upscale text)

[Disonantemus]

I want to use the model 8x_NMKD-Typescale, because is the best to upscale text.

I was able to convert and use many ESRGAN models to NCNN using ChaiNNer.

I was able to convert 8x_NMKD-Typescale to NCNN in the same way, but Real-ESRGAN-ncnn-vulkan doesn't support 8x scaling, I did This Issue there, but project has no activity (since 3 years).

I'm no programmer, and I don't know how to do this.
Maybe I'm wrong asking for this here, but I don't know where else to ask.

Thanks in advance,
Nice project!

Both Real-ESRGAN-ncnn-vulkan and upscayl-ncnn only support 2-4x for now, maybe I could have a try of adding 8x by some copy-and-pasting in realesrgan.{h,cpp} and then make a custom build by myself?

I'll try it when I have enough spare time. It should help if you can attach the converted NCNN model.
