active_predictors(), as.party(), extract_rules(), and var_imp() now have methods for catboost models (catboost.Model).

Symmetric and non-symmetric trees are supported, as are one-hot encoded categorical splits; splits based on categorical target statistics (CTRs) cannot be converted to rules. We added support for most CTR splits.

Relies on a non-CRAN package (catboost) 🤞
