HuggingFace integration

[not-lain]

This PR will allow your model to be available on huggingface making users to access it with ease.
the PyTorchModelHubMixin will add 3 methods to your model similar to the transformers library :

• push_to_hub
• from_pretrained
• save_pretrained

to help you setup your model on the hub you can follow the instructions in this colab notebook :
https://colab.research.google.com/drive/1FmInXvJ1v6WJ7TbqXAVvIrth7kwO_Scx?usp=sharing

By using PyTorchModelHub you can get access to :

• know how many times your model has been downloaded from huggingface each month
• filter huggingface and check how many deet models exist on the hub

If you have any questions or feedback feel free to let me know.
