Test FLOPS Aero Builder

[xjjiang]

Summary

Added a unit test file for FLOPS based aerodynamic builder (20 unit tests).

Note: the unit test file for GASP based aerodynamic builder has to be put on hold because it depends on the consistency of default values in several GASP based components.

I could use a second opinion on the use of _unspecified from another reviewer

If I add 'units': units, I get the following errors:

   'traj.phases.climb' <class Phase>: Output units of 'unitless' for 'traj.phases.climb.param_comp.parameter_vals:aircraft:nacelle:characteristic_length' are incompatible with input units of 'ft' for 'traj.phases.climb.rhs_all.solver_sub.core_aerodynamics.Mux.aircraft:nacelle:characteristic_length'.

If don't, unit test for FLOPS aero builder fails.

I have to come back to it later.
