DLC Generation - Refactor and New Cases

[dzalkind]

Purpose

Refactoring of the DLC generator to follow the case input structure commonly used in aeroelasticse. A few new cases have been added so far, but the previous functionality should be implemented already.

Starting a draft PR to evaluate what tests are failing with new method.

Items to do:

• documentation of new configuration and setting up of new cases
• comparison with old DLCs to verify new method
