GitLab

- Add example of usage
- Update metrics

- I added an example using the model with pipelines to show that we have set```{"use_fast": False}``` in the tokenizer.
- I added a Colab to play with the model and pipelines
- I added a Colab to discover Huggingface pipelines at the end of the document

I trained the model for more epochs so I improved the results. This commit will update the results of the model and add a gif using it with **transformers/pipelines**
