------------------
* Add prediction set estimation for binary classification.
* Add Learn-Then-Test method for multilabel-classification.
* Add documentation and notebooks for LTT.
* Add a new conformity score, ResidualNormalisedScore, that takes X into account and allows to compute adaptive intervals.
* Refactor MapieRegressor and ConformityScore to add the possibility to use X in ConformityScore.
* Separate the handling of the estimator from MapieRegressor into a new class called EnsembleEstimator.
* Rename methods (score to lac and cumulated_score to aps) in MapieClassifier.
* Add more notebooks and examples.
* Fix an unfixed random state in one of the classification tests.
* Add statistical calibration tests in binary classification.
* Fix and preserve the split behavior of the check_cv method with and without random state.
