any plan to implement other complex upscale algorithm

[asukaminato0721]

Just a crazy thought.

I found ESRGAN shows good effect.

pros:

• good result

cons:

• slow, so fit for those low fps games
• complex

and I found a cpp implement https://github.com/Qengineering/Real-ESRGAN-ncnn-Raspberry-Pi-4

Stuff like ersgan is not temporally stable though? It wouldn't make much sense at all.
