Incorporate changes from pvlib/pvlib-python#1168

We'll need a model object to handle the array_losses_parameters for PVArrays. This should probably be a simple ArrayLosses class with the dc_ohmic_percent property.

Dashboard changes:

  • Add an ArrayLosses class.
  • Need to add array_losses_parameters property that is valid only when not an otherwise PVWatts Array.

API Changes:

  • ArrayLosses Model class.
  • Validate that array_losses_model is non-existent when expected. Possibly need to check this at the inverter level where the PVWattsLosses exist and verify that both are not declared.
  • Set the PVArray's dc_ohmic_model to dc_ohms_from_percent when array_losses_parameters is provided.
