This PR allows setting timestep_hours on the InferenceEvaluatorAggregatorConfig, which if set to a value other than 6, will modify the step selected for "step_20" metrics.

This does mean "step 20" is a lie in these cases. While not ideal, renaming this metric is also problematic because in coupled modelling we rely on reporting step 20 ocean metrics. This is more problematic than in our daily-step runs (which are still preliminary) having to remember and communicate that "step 20" really means "day 5" (which we generally understand, internally). We should rectify this in a later PR adding more configurability to select the desired lead time.

Changes:

  • Added timestep_hours to InferenceEvaluatorAggregatorConfig, which if set to a value other than 6, will modify the step selected for "step_20" metrics.

  • Tests added
