Sort the files and save the .bin model file for backwards compatibility

[cwognum]

Changelogs

• Tried fixing cannot download model #84
  • See the issue for more details, but the ultimate fix was just to reupload the featurizers.
• Also save the .bin files, as with transformer>=4.35.0 the default has changed to .safetensors and we want to remain backwards compatible.

Thanks @cwognum.

Can you confirm it solves the issue ?

[maclandrol]

Can you pin the version of datamol or fsspec here ?

The test GH action succeeds again.

Also tested it locally with:

import datamol as dm

from molfeat.trans.pretrained.hf_transformers import PretrainedHFTransformer

# Load a pretrained model
model = PretrainedHFTransformer(kind="ChemGPT-4.7M", notation="selfies", dtype=float)
feats = model.transform(dm.data.freesolv().iloc[:100].smiles)
print(feats)

So the issue is solved, but not per se because of the changes in this PR.
