Integrate with huggingface

[not-lain]

this pr will integrate your model with huggingface using PyTorchModelHubMixin.
by inheriting from PyTorchModelHubMixin you can access 3 main methods similar to the transformers library which are :

• from_pretrained
• save_pretrained
• push_to_hub

Additionally, sharing your model on huggingface will add more visibility and ease of access to your model, you can also keep track of how many people have downloaded your model each month.

If you have some checkpoints you want to put on huggingface, I added a step-by-step colab notebook explaining how you can do it in here

Finally, I wanted to express my astonishment at achieving state-of-the-art performance, awesome work!
