Future Warnings - change frame.append to pandas.concat in filters.py, elsewhere.
Getting this warning when building a filtered dataset:
/Users/pye/miniconda3/envs/newipy3/lib/python3.10/site-packages/resonate/filters.py:102: FutureWarning: The frame.append method is deprecated and will be removed from pandas in a future version. Use pandas.concat instead.
