docs: Build a Binomial ModelMetrics object from target-class probabilities, from actual labels, and a given domain for both labels (and domain[1] is the target class)
  @param targetClassProbs A Vec containing target class probabilities
  @param actualLabels A Vec containing the actual labels (can be for fewer labels than what's in domain, since the predictions can be for a small subset of the data)
  @return ModelMetrics object
