[DATA EXTRACTION] add all_days & all_daily_series property, that was useful to extract some data of snow depth for taline

[PAPER1][STARTING YEAR] write main for location & scale with common starting year spatially & altitude

[NON STATIONARY] fix constant gev params. also some refactoring for the regions, the colors, and functions.

[EUROCODE DATA] add eurocode regions, and mapping between massifs and departement, and mapping between departement and eurocode region.

[GEV TREND TEST] add gev trend test two parameters (for Location and scale parameters). IMPORTANT: Now the definition of test sign correspond to the sign of the strength (i.e. the increase with respect to some quantile)

[GEV TREND TEST] rename and refactor the code for one parameter gev trend test (to prepare the introduction of tests with two parameters)

[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
