Addin H-optimus-0 Model

[stergioc]

This is adding the H-Optimus-0 model for tile feature extraction.

Ah right! The timm library is not available by default in sopa :|

We might need to re-write the ViT giant class here to avoid the timm dept

How giant is it? If it's too big, we can consider the option of only checking if timm is installed, and send an appropriate error log if not (something like ERROR: Using the hoptimus0 model for inference requires installing the timm dependency, this can be done via 'pip install timm')

Sorry, I mean the class of the ViT variant giant that is used by the h-optimus-0. The solution of adding the timm library as an optional requirement in case this model is selected for inference seem to me the best tradeoff. I will update the PR :)

Oh I see, sorry for the misunderstanding!

Looking good now, I'm merging :)

Ah, maybe we need also to update the docstring for the compute_embedings function.

You're right, I just updated it directly on master
