Add option to calculate AEP as described in the European Wind Atlas, page 95. This method calculate the power x weibull_weight using linear instead of constant power segments

add cutin, cutout and upct_tables in WindTurbines.from_WAsP_wtg + add idle trust below cutin and above cutout

Reduce memory consumption in PropagateDownwind by doing inplace flattening of dw_iil, hcw_iil and dh_iil. Note that this may have side-effects in the parent functions

Before the result of the GridInterpolator was transposed for 1 additional dimesion and mixed for more. This has been fixed

before default rotor center was shared among wind farm models, i.e. wakedeficit model of last instance was applied to all instances

renamed GCLDeficitLocal to GCLLocalDeficit
renamed NOJDeficitLocal to NOJLocalDeficit
made NOJLocalDeficit subclass of NiayifarGaussianDeficit to reuse k_ilk function
add tests to test_deficit_models.py

add function to create XRSite from simulation_result.flow_box() allowing precalculated sites including effects of neighbouring farms
