Add Sudo Models

[Pete4K]

Will it be possible to add the Sudo models here, too:

like a variant for Real ESRGAN Anime Plus x2: https://openmodeldb.info/models/2x-sudo-RealESRGAN
https://openmodeldb.info/models/2x-sudo-RealESRGAN-Dropout
this Real Cugan model: https://openmodeldb.info/models/2x-sudo-shuffle-cugan-9-584-969
I think these models look also great to try.

These models are long-trained models, so maybe they are a good alternative for the slow-running anime plus and the slow-running Cugan, when they are faster. But that could be. And it is a solution for anime plus 2x version. Maybe it could be tested, if RealESRGAN-Dropout or the "normal" RealESRGAN variant is better. I think the sharpness is between the oversharpness of anime plus and animevideo.

Thanks for opening a separate issue. My concern over this that we could get requests to add any model, and I don't have an infinite amount of time to add just any model anyone suggests. We need some kind of criteria to determine if something needs to be supported officially. Be it a new algorithm or model.

Ok,I think that these Models of Real Cugan and Real ESRGAN look a little better than animevideov3 maybe and is close to Anime Plus. Furthermore it is like an Anime Plus 2x, which doesn't exist and maybe it is faster. Like you said I wouldn't implement every Model which is possible, but I think that these are high quality ones and that's worth it. Also thank you very much for all the time you spend in it.
