[contrasting project] remove the restriction of maxima to winter. because i will focus only on snowfall so i don't really need that restriction

[contrasting project] generate plot for the trends in return levels for the winter extended. do the same for the distribution of wps. remove winter_maxima and summer_maxima in abstract_study.py

[contrasting project] add main_distribution_wps.py to study the (spatial and temporal) distribution of weather patterns that are causing maxima in the different region of the French Alps

[quantile regression project]  final modification. attempt to add multiprocessing. but results are not conclusive

[quantile regression project]  fix bugs in daily_observations.py for the creation of the coordinates for the daily fit. some fix to prepare for some potential non stationary exponential model one day

[quantile regression project] add test exp simulations (stationary and non stationary) for models on annual maxima. Prepare the code to fit with non stationary exponential models

[contrasting project] fix memory issue that was happening while loading many precipitation studies. issue #300

[quantile regression project] refactor simulations. add transformed coordinate to the quantile functions

[quantile regression project] refactor imports for quantile estimators. two fix: nb_obs=1 in GevSimulation.py and df_merged correspond to df_coordinates from now on (such as it takes into account the transformation if there is one)

[refactor] remove scores. remove non_stationary_trends, delete univariate_test_results that was deprecated
