Use Battery model in PySAM

[mnblonsky]

It would be great to natively use PySAM's battery model. It should include all of the same features as our model, plus more. A few things to verify that it can do:

• Run single timesteps
• Capacity degradation (while running single timesteps)
• Thermal modeling with exogenous ambient temp
• Resetting to previous state
• Prediction of next SOC, efficiency, and remaining energy (could run and reset to do prediction)
• (optional) SOC setpoint instead of power setpoint
• (optional) Generator or Fuel Cell models??

Once we implement, it'd be great to remove equipment.parameters too.
