To include other vision transformer models

[rishikksh20]

Hi @rosinality, hope you are doing well! I really like your repo, especially for dataloader and augmentation part for image classification. I am not majorly working on Vision field but still I have implemented some of the vision transformer models, following:

• https://github.com/rishikksh20/convolution-vision-transformers
• https://github.com/rishikksh20/CeiT-pytorch
• https://github.com/rishikksh20/CrossViT-pytorch
• https://github.com/rishikksh20/ViViT-pytorch And happy to include all these into this repo.
