Convert LightGBM to CatBoost to use CatBoost fast appliers
- Convert LightGBM to CatBoost, save resulting CatBoost model and use CatBoost C++, Python, C# or other applier, which in case of not symmetric trees will be around 7-10 faster than native LightGBM one.
- Note that CatBoost applier with CatBoost models is even faster, because it uses specific fast symmetric trees.
