Add Image Upscaling AI for faster High-Res renders (like ESRGAN)

So I was recently watching Octane 2019 presentation there was mentioned image upscaling AI that can save a lot of rendertime when making a High Resolution image. It was a great idea and I've also remembered that there are also free and opensource projects that can do this like ESRGAN. The only problem with it is that it's another program to install (especially with all that extra things you have to install in order to make it work) so it would be awesome if blender had something like this build in.

I know it would be a lot of work to create something like this but it would be nice addition for some next generation of blender.

I'm also staring to study CS so if I learn more I would try in my free time to do something like this in blender but if someone reading this have an idea for that and is more experienced it would be awesome if you would help.
