Load Image Classification Dataset from Local 
Opening this back up, since I'm planning on tackling this. Already posted a quick version of it on my account on the hub.

```python
from datasets import load_dataset

ds = load_dataset('nateraw/image-folder', data_files='PetImages/')
```
**Is your feature request related to a problem? Please describe.**
Yes - we would like to load an image classification dataset with datasets without having to write a custom data loader.

**Describe the solution you'd like**

Given a folder structure with images of each class in each folder, the ability to load these folders into a HuggingFace dataset like "cifar10".

**Describe alternatives you've considered**

Implement ViT training outside of the HuggingFace Trainer and without datasets (we did this but prefer to stay on the main path)

Write custom data loader logic

**Additional context**

We're training ViT on custom dataset
