Added new unit tests in `tests/features/test_labeling_schemes.py` to cover `calculate_future_returns`. The tests verify normal behavior for multiple horizons, handling cases where the dataframe is smaller than the horizon without crashing, and handling missing required columns. Also cleaned up binary `__pycache__` artifacts from `features/`. Co-authored-by: maghdam <63883156+maghdam@users.noreply.github.com>
