Added Ensemble Model

New

• At an additional cost, you can now ensemble both of our models into one forecast with higher accuracy. This is slightly slower than the advanced model by itself, but should generally be favourable over either as it smoothens out any extreme outliers impressively well. Internal and beta testing yielded 17% improvement over advanced model and more than 50% improvement over standard model.
• New model=ensemble field in forecasting and batch endpoints to use ensemble model
