landing_gear_design: implement a low fidelity method

TODO

Summary

As discussed in the UNICADO workshop https://git.rwth-aachen.de/unicado/unicado-package/-/issues/46, a simpler "low-fidelity" method for the LG shall be implemented acc to the minimum parameter the other tools need (similar to #152 (closed)). Following ideas could be used as a starting point:

• empirical mass estimation e.g. acc to Torenbeek 1982 (section 8.4.1 (e) has for both main and nose gear an estimation depending on MTOM)
• simple positioning
• simple geometry (length ?)
