Description

I added a re-optimization for each X_n+1 at inference time (in the predict). The old split method is still available with mapie.predict(X, unsafe_approximation=True).
Fixes #506

Warning:

In this tutorial, we use ``unsafe_approximation=True`` to have a faster
computation (because Read The Docs examples require fast computation).
This mode use an approximation, which make the inference (``predict``) faster,
but induce a small miscoverage. It is recommanded not to use it, or be
very careful and empirically check the coverage and a test set.

I needed to temporally use the old method (with unsafe_approximation=True), which doesn't have the theoretical guarantees, otherwise the documentation was in timeout. I will need to change the dataset, to have faster computation, or transform this .py tuto in the doc, into a true notebook, which is not run during the documentation build.
Indeed, showing in the first tuto, the deprecated method which doesn't have guarantees is not a good idea.
