[PAPER1] modify the strength criterion for the hypercube (use the 0.98 quantile and its evolution in 10 years)

[GEV] add computation of the mean & variance. modify gev_estimator. add function visualize_summary_of_annual_values_and_stationary_gev_fit: to quickly visualize the repartition of the main empirical indicators and corresponding stationary gev indicators.

[HYPERCUBE VISUALIZATION] improve trend repartition for poster by printing the optimal year. plot in higher resolution with text on the figure

[HYPERCUBE VISUALIZATION] modify first starting year for the full parameters. add main starting years to study cluster of starting year for a single altitude for a recent SWE (RSWE). add colormap for display

[QUANTITY HYPERCUBE] order the dictionary of reduction functions. add detailed plot parameter. fix plot with multiple reduction functions

[HYPERCUBE] add first and last year argument. add exact year argument. fix ploting issues in altitude_hypercube visualizer. add quantity extended visualization.

[CHANGE POINT TEST] improve management of crash mode, to avoid crashing all the run (issues with test with scale parameter)

[HYPERCUBE] add AltitudeHypercubeVisualizerWithoutTrendType (and its extension) to visualize log likelihood evolution. add new altitudes bands for the extended plots. add constrained plot argument when creating multiple plots.

[HYPERCUBE] implement vsualize_year_trend_by_regions_and_altitudes. run main hypercube for all settings

[HYPERCUBE] refactor hypercube. add the fact that for the fast mode, massif names are sampled randomly for the fast mode. this enables to explore the change point test results under different viewpoint.

[COMPARISON] add some labels to the graph. add trend type agreement/classification graph. refactor column name

[COMPARISON] add class_property to abstract study, to enable spatial display of errors between SAFRAN reanalysis & data from observations
