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

Implemented wake_radius() function for the different wake models and modified args4turb to be independant from deficit

add selfsimilarity blokage model
prepare for gradients
New structure. Old WakeModel mainly in new EngineeringWindFarmModel
add deflectionmodel
update documentation

Prepare for iterative calc_wake backend by adding an the source-wt dimension(i) to all calc_deficit arguments

Solve two issues in noj: 1. variables passed to np.arccos() could be lareger than 1.0 or less than -1.0 for some combination of R1, R2 and d to cal_overlapping_area_factor. 2. Ct values passed to np.sqrt(1-Ct) could be larger than 1. These two issues both result errors/nan values. Now these variables/values have to pre-treated to avoid such results.

deleted test_examples.py as all example modules are tested in test_main.py

- ti_map added
- default ti changed from 0.75 to 0.075
