AeroCases: Multiple remainingContributions

[MarAlder]

cpacs/vehicles/aircraft/model/analyses/loadCases/aeroCases/aeroCase/aeroData/vehicle/coefficientsBreakdown/remainingContributions:

As a feedback to the last stakeholder meeting, @elPlaneador proposed to add a remainingContribution node below remainingContributions in order to allocate the contributions more closely to individual components that cause these contributions.

One drawback is that the components in question are not explicitly specified via the CPACS schema, making automated interpretation of the content difficult. I recommend collecting specific components (antennas, sensors, etc.) when applying the feature in practice, so that if they are used too laxly in practice, an additional enumeration can be added that explicitly specifies what exactly causes the remaining contribution.

No contradiction, so I assume we can adopt the remainingContributions in the v3.3-RC version.
