SCOPE: this utility gets the final risk levels and risk labels from ROC optimization

Use the steps from running SCOPE to obtain the final ROC-optimized risk factor and risk labels.

In this example, it is assumed that SCOPE returned fusion at level 1, then on the new risk factor fusion at level 2. Using the test variables as the input arguments:
riskfactor = [1 2 3 4 5 1 2 3 4 5 1 2 3 4 5]
risklabel={'ajcc 1','ajcc 2','ajcc 3','ajcc 4','ajcc 5'}
binaryfusionsteps = [1 2]

The result is as expected: binaryfusionrisklabels = 'ajcc1' 'ajcc 3' 'ajcc 5'
