[contrasting] harmonize gumbel altitudinal models. create plot_total_aic.py. remove exception for model with infinite aic.

[contrasting] add quadratic & cross terms Gumbel altitudinal models & fix a recurrent bug that happenning when checking the AIC value

[contrasting] add Gumbel altitudinal models. But so far only the first three models are passing tests (models with quadratic & cross terms are crashing)

This includes models that combine some quadratic aspect & a cross term.
Remove random test

the selection for the model with minimal aic only takes into account models with with finite aic (there are often several models with infinite aic)

[contrasting] aic and bic test ok for my first model combining a linearity in 2 different coordinates.

[contrasting] fix polynomial_margin_model.py creation. extend the form_dict for spatio temporal models.

[contrasting] add quadratic model for gumbel/gev and location/scale. modify code for the name of the models

[contrasting] add assertion that the max_abs_change is different from np.inf otherwise it makes the computer freeze
IMPORTANT MODIFICATION, THAT MIGHT CHANGE PAPER 1: change unconstrained_estimator_gev_params to unconstrained_estimator_gev_params_last_year
