• Description: Simulators for kite power systems
• Release notes:

#### Changed
- the build script now only installs `matplotlib` if it is not yet installed on the system
- improved the example `joystick.jl` and its documentation
- bump KiteControllers to 0.2.10
- bump KiteModels to 0.6.6  
A new kite model (KPS4_3L) was added, that uses three winches at the ground to steer the kite.
The new variant (version 3) of the KPS4 kite model allows to define polars that do not depend on the steering input, which makes it easier to define new kites.
- bump KitePodModels to 0.3.3  
A simplified KitePodModel was added with a linear relationship between depower setting and depower angle, which makes it easier to define new KCUs.
#### Added
- a new, torque controlled winch model
- you can now define the diameter and the aerodynamic drag coefficient of the KCU
- plot `aerodynamics`
#### Fixed
- changes of the polars had no effect
- changes of ```max_steering``` had no effect
- fix example `compare_kps3_kps4.jl`
#### Braking
- the function `next_step!` now requires either the parameter `set_speed`, which replaces `v_ro`, or the parameter `set_torque`, depending on the question if you use the `AsynchGenerator` or `TorqueControlledWinch` in the settings
- the function `init_sim` has the new parameter `delta`. It should be between 0.0 and 0.03 and defines the pre-tension of the tether. The parameter `stiffness_factor` should be between 0.1 and 1.0 and not longer smaller than 0.1.
- the constructor `FPCSettings` now requires the named parameter `dt`
- the constructor `SystemStateControl` now requires the named parameter `u_d0` and `u_d`
