[contribution] gradio interface modified to batch process an image folder

[Mixomo]

Hello, I have made a modification to the app.py with a second tab that allows to batch process a folder of images, with its respective progress bar.

I really think this is one of the most powerful and efficient upscalers recently. Very good image quality, I was impressed. Amazing work.

I made this modification mainly to test and process frames extracted from a low resolution video.
The quality of the individual frames are very good, however when joining them together they suffer many variations that are noticeable when playing the video.
I tried with a fixed seed, but still with the same result.
I guess this is the nature of the model, since it is obviously designed to enhance images and not videos. However, I think this approach has a lot of potential, and it would be great in the future to see an implementation for video.
If it weren't for those differences in joining them, it has better quality than paid models like those of Topaz Labs.

Thanks for your contribution. I have updated this demo in our repo.

To deal with video, it is necessary to introduce more designs to ensure video consistency. We may explore this in the future. @Mixomo
