Changing the name of AEPCalculator to avoid clashing with the new AEPCalculator of PyWake
PyWake has introduced a new class also called AEPCalculator, which does not have the same API as Topfarm2.cost_models.utils.aep_calculator.AEPCalculator. I propose to move the Topfarm2 AEPCalculator into the fused_wake_wrappers.py file and renaming it FusedWakeAEPCalculator.
