Add Allociné Dataset
great work @TheophileBlard  LGTM, thanks a lot for adding dummy data tests :-) Was it difficult to create the correct dummy data folder?  It was pretty easy actually. Documentation is on point !
This is a french binary sentiment classification dataset, which was used to train this model: https://huggingface.co/tblard/tf-allocine.

Basically, it's a french "IMDB" dataset, with more reviews.
