[paper 1] add upper and lower bound into the gev param object. Add script to run fit wihout maximum, and then compare the upper bound with the maximum values that was removed. The test is ok for all altitudes, the upper bound found was always higher than the maximum values

[paper 1] refactor study visualizer using "model subset for uncertainty" name instead of unclear names.

[Confidence Interval] use fix r.ci.fevd.mle_fixed for the Gumbel case in the Python code. fix the R code one more time for the gradient

[PAPER 1] add gumbel type for mle fit. add study_visualizer_for_shape_repartition both for gumbel VS stationary and stationary VS non-stationary

[PAPER 1]  add dpi=1000 to every plot from the paper for image quality. add some fix ylim when plotting return level for the Maurienne

[PAPER 1] improve uncertainty plot. fix eurocode value for the histogram. modify number of bayesian iterations to 20000 for uncertainty plot

[PAPER 1] fix gelman convergence score formula, take the variance instead of the std. improve bayesian display

[PAPER 1] add params_start_fit_bayesian for gelman convergence. add some random init param for the beginning of the MCMC chain.

[PAPER 1] refactor folder names in the paper snow load folder. add mani gelman convergence test. add the possibility to change the number of iterations for the bayesian fevd estimation

[PAPER 1] fix quantile for snow load in the case where psnow < 1 (i.e. for the mixed distribution case)

[PAPER 1] fix the code for taking the argmax of some value. add some new classes for making comparison between various snow variables

[PAPER 1] taking into account psnow when computing TDRL and also when computing return level uncertainties
