Add skeleton bone information to annotation

[Kokika]

What feature are you suggesting?

Overview:

Acces skeleton bones from UE.

Smaller Details:

I am using and implemented skeleton bones from another Airsim variant and I would like to bring it here.
I am working on pr.

Nature of Request:

Should I create another Annotation struct or add to extend the existing one?
The information can be hold with std::vector<std::pair<std::string, Vector2>> skeleton;
Do we need Vector3 information to the bone?

Why would this feature be useful?

Useful for machine learning.

Hi @Kokika. Thank you for your willingness to contribute to the project; we are truly doing it together.
we’re interested in reviewing the contribution, but merge decisions would depend on the design quality, performance impact, and how well it fits the existing architecture.
It would also help to clearly define the expected output format (2D projected bones, 3D world positions, optional/disabled by default, etc.).

Hi @jonyMarino. I am happy to hear it. I had prototype, but not finished so later I gonna come back with clean pr for this feature.
I bring these changes from Cosys airsim, where I already worked for me. I am trying to adapt to clean architecture design for IAMAI Airsim.
There are 2D projected bones in annotations, access function for 3D world position, animation control, etc. Currently I am working on machine learning test project for these features.
