Add Part 7 demonstrating feature_importances() method for RandomForestRegressor to improve example consistency and showcase interpretability features for regression tasks.
This makes the regression example consistent with the classifier example (random_forest_iris.rs) which already demonstrates feature importance in Example 5.
Changes:
- Add Part 7: Feature Importance section with housing price example
- Display importance for sqft, bedrooms, bathrooms, age features
- Show practical use cases for feature selection and interpretability
- Update summary to mention feature importance capability
- Renumber OOB section to Part 8
