Extra problems

[tomMoral]

It would be nice to have another problem to compare the same solvers with different problems.
ImageNet is probably a very good starting point + adding some of the CIFAR10/CIFAR100 results

• Train a ResNet50 with AdamW with ImageNet/Cifar10/Cifar100
• Train DiT with MuOn

We trained a DeiT using Scion in this repo:
