[Feature Request] Curriculum Training for Augmentations

[Kim2091]

The ability to change which augmentation preset is being used at different points in training would be great. For example, at 10k iterations, resrgan_blur could be used, but at 30k it's automatically switched to bsrgan_blur.

This was discussed in the #trainner channel on the GU Discord server

Edit: A possible expansion on this idea, augmentation preset strengths. I'm not sure how it'd function, but I figured I'd bring it up
