Write for each function in rtichoke the same function for plumber api

[uriahf]

Write new logic for stratification with lists, not data frames.

Prob. Threshold / PPCR

[uriahf]

Naming Convention: besides create_summary_report() all the post endpoints will be called by the original function with the suffix "lift": plot_roc_curve() -> plot_roc_curve_list(). This convention indicates that the api returns a json array and not a plot, but the suffix indicates that the inputs are identical to the functions in the original rtichoke r package ("create_""prepare_" indicates probs and reals as input, "plot_" indicates performance data)

Discrimination:

ROC

• create_roc_curve()
• plot_roc_curve()

Lift

• create_lift_curve()
• plot_lift_curve()

Precision Recall

• create_precision_recall_curve()
• plot_precision_recall_curve()

Gains

• create_gains_curve()
• plot_gains_curve()

Calibration

• create_calibration_curve()

Utility

• create_decision_curve()
• plot_decision_curve()

Summary Report

• create_summary_report()

Performance Data

• prepare_performance_data()

[uriahf]

All the following inputs should be supported:

• 'by'
• 'col_values'
• 'size'
• 'min_p_threshold'
• 'max_p_threshold'
• 'output_file'
