Enabled user tweaking of isolation parameters

- Encapsulated the "steinberg" and "simple" techniques into a master "isolate" function that is defined by the passed in isolation parameters
- Renamed calc_local_scores() to generate_automated_labels()
- Reworked generate_automated_labels() to take in the isolation parameters dictionary
- Reworked local_score_visualization() to take in the isolation parameters as well as the master isolate() function.
- Deleted the calc_local_scores2() and local_score_visualization2() functions that were designed to demonstrate the simple isolation technique.
- updated jupyter notebook tutorial to demonstrate above changes.
- removed the second howler monkey example clip visualizations as well as the demonstration of "catch" scores since they seem redundant and inflated the size of the tutorial
