* feat(Transformations): removed feature-selection pre-processing step completely
* fix(Core): removed unnecessary `original_X`
* fix(Transformations): use the X_expanding_window to transform subsequent data
* fix(RFE): should check for model correctly
* fix(Config): only re-train the model every 40 timestamp
* fix(MetaLabeling): pass in the correct X to meta-labeling step
* fix(Transformation): PCA should at least keep as many features as sliding_window_size
* feat(Transformations): cache transformations across the same asset
* fix(Tests): missing preloaded_transformations arg
* chore(Config): got rid of unnecessary 'classification_models' and 'regression_models' dictionary keys
* feat: Added optional import of models.
* fix: Models weren't wrapped into abstract class, fixed it.
* chore: Deleted leftover comments.
* fix: Same merge commit as on remote.
* fix: System wasn't putting in RF because there was no differentiation between RF as regressor and RF as classificator.
* fix(Models): use the XGBoostModel wrapper

* refactor(Naming): use `primary_models` & `meta_labeling_models`
* refactor(Naming): using primary * meta_labeling across config and in pipeline
* feat(Pipeline): added back Ensemble models
* fix(Pipeline): compiler error
* fix(Config): typo
* chore(Pipeline): removed unused averaging step
* revert the changes in discretizing
* chore(Pipeline): remove sharpe improvement logging
* fix(Pipeline): ensemble predictions should be a pd.Series instead of a DataFrame
* fix(Pipeline): discard unnecessary ensemble_probabilities
* fix(Pipeline): fixes regarding various meta-labeling ensemble bugs
* fix(Reporting): use the new naming convention
* fix(Reporting): use the right variable
* feat(Sweep): new sweep for ensemble models
* fix(Sweep): config reference
* fix(Config): simplified dev config
* fix(Models): use the faster LR model
* fix(Models): use LGBM in the meta-labeling model for speed
* fix(Selection): always use the first model for feature selection, commented out caching from select_features() as it's close to redundant in terms of speed
