Description of the new feature / enhancement

The program can further impress users by adding a feature that uses Real-ESRGAN to improve image quality. This feature would create a new folder with rescaled images. Although the process may be a bit slower, the results are impressive. Real-ESRGAN is a powerful tool for improving image quality. There is also Real-CUGAN available here, which can provide similar features.

1. Fellow user, no offence, but this feature request is impractical.

2. I honestly think it would be very hectic and time consuming to integrate an upscaler like RealESRGAN into Yomikiru as it is maintained by a single developer, And asking the dev to work on a project of such large scale with the little time he / she might have on hand to maintain the already complicated Yomikiru is impractical.

3. Why start from scratch when there are already many upto date and actively developed GUI's of RealESRGAN.

4. For example, Upscayl or waifu-2x uses RealESRGAN and other image upscalers you could choose from.

5. It would be better to use one of the actively developed GUI rather than starting from scratch. You could upscale the manhwa you want with it and place it in a folder of your choice and then read it in Yomikiru. This is the best solution.

Unfortunately what @omodia said is true.
These days I'm not even getting time to fix the existing issue let alone implement something this big. Plus, it will require python packages, I don't have much experience in that either and app's size will be too big with those included.

However, there's #245 which is similar to this and will improve quality. And in my opinion, it will be better to use existing GUI instead because in the end I will need to save those upscaled images on drive to display them either way.
