Thanks to the new attributes (and corresponding `suggest_with_optuna()` arguments) `suggest_low` and `suggest_high`, we enforce the possibility of suggesting lower or upper bound. Indeed, by default, optuna will suggest inside the range (low, high) but never reach exactly a bound (except if a step was provided). To achieve this, a derived categorical hyperparameter is suggested under the hood to decide whether suggesting the lower bound, upper bound, or a float in between. The "generated" hyperparameter will be named as the original hyperparameter, suffixed with ".suggest_bound" and will take as values - "low": lower bound suggested - "high": upper bound suggested - "": usual behaviour
