integrate the area under coverage curve to produce a single number that represents the relative expected confidence of the model.

@voetberg is this equivalent to the coverage fraction in https://github.com/deepskies/DeepDiagnostics/blob/main/src/metrics/coverage_fraction.py?

[bnord]

@beckynevin what does the coverage_fraction code calculate?
