v4.4

FLORIS v4.4 introduces two new turbine operation models, the ControllerDependentTurbine model and the UnifiedMomentumModelTurbine, developed at TUM and MIT, respectively, to FLORIS. These provide exciting options for advanced modeling of how turbines operate when yaw misaligned and derated.

Also included is a beta feature for representing the variable operating cost (VOC) of a turbine and optimizing for net revenue given operating costs. Finally, a bug fix for wakes of turbines implementing active wake mixing is included.
