propulsion_design & aerodynamic_analysis: shift nacelle drag to net thrust

TODO

Summary

As discussed in the UNICADO workshop https://git.rwth-aachen.de/unicado/unicado-package/-/issues/46, currently the nacelle drag is included in the aerodynamic analysis. The idea is to shift this to propulsion design and include it into the net thrust
