New feature: apply external forces to the system at runtime

[ArturoMS13]

This new feature allow the application of external forces to the system computed at runtime based on the state of the system at each time step.

In particular, forces related to floating dynamics of wind turbines (mooring lines, hydrostatics, hydrodynamics and wave forces) are considered.

This PR Fixes #112 including the possibility to change the direction of gravity.

It also includes other minor changes:

• Include lumped masses defined by a 6x6 mass matrix through the structural input variable lumped_mass_mat
• Possibility to skip the writing of the aerodynamic wake in SaveData through the save_wake setting.
• Generate spar floating wind turbines with the template_wt library.

It updates some packages in the conda environment.

Requirements before merging

• Update UVLM library
• Clean up
• Merge PR New feature: apply external forces to the system at runtime #125 (multibody) before this one
