OM Refactor: Scale Simulation Results

Feature or improvement description

Added a 3 new subsystems to the cluster 'simulation' component. One of these is a new model, called a degradation combiner. This does two calcs:

• adds the cell voltage and the degradation voltage.
• calculates the power from the combined voltage

The two other subsystems utilize the CombineSerialComponents component to scale cell-level simulation results to the cluster level. The power and voltage from the degradation combiner are input to the first scale-up component, and the current density, hydrogen production, and o2 production from the cell_real component are connected to the first scale up component. The first scale up component is connected to another scale-up component (stack to cluster). The last scale-up component promotes the outputs from a naming convention of {var}_out to Cluster_{var} (so the cluster-level simulation outputs are named Cluster0.simulation.Cluster_H2 for example).

In the future, the H2 and O2 would be connected to the scale-up component from a losses group, the subtracts hydrogen losses due to warm-up delays.
