Auto Split into Train/Val/Test Sets

[jquaglia-uss]

One of the things that makes training models more tedious and time consuming is dataset prep. Mainly, resizing images and putting them into the proper set (Train/Val/Test). A massively useful feature would be to have this step automatically done during upload.

Current functionality is specifying a folder that already contains train/val/test sets.

Useful enhancement of the product would be the ability to just select a folder of labeled images (this is probably most useful for classification tasks) and the upload process could resize/assign splits for the user.
