Add wake oscillator feature

[mvanzulli]

This enhancement issue seek to generalize the ONSAS implementation in order to include the Wake Oscillator Model as an improvement of the aerodynamic forces.

• add VIV function
• change authorship list
• change global VIV variables in hydroframe force to official fields in the input structs (analysissettings)
• add initial $q$ value
• include back a nonlinear aerodynamics test-example

Not to be implemented yet.

I'll reopen this issue with a different approach. just including the WOM computation as an additional feature but not as monolithic by the moment.

[jorgepz]

advances done in #504

[jorgepz]

the VIV function was added by @TheChikenfly in #518
we have yet to update the authorship list before closing this issue.

[TheChikenfly]

Amazing thanks!

[jorgepz]

We just fixed/optimized ONSAS assembler flow. and also updated the authors list.
To this issue description I just added "change global VIV variables to official fields in the input structs" . we can discuss this later.

[jorgepz]

we discuss with @TheChikenfly and @mvanzulli and decide to leave qvect as global variable by the moment

[mvanzulli]

I think we need to add a simple problem into tests. I've been changing some files and the VIV feature is not being tested

[jorgepz]

Indeed! That is very important.

I added a subtask to improve the VIV feature considering #596
