OpenSCENARIO 2.0 supported

[synkrotron]

Description

We supported OpenSCENARIO 2.0 standard in this feature.
We implemented a compilation system to compile and execute osc2's code, and implemented part of the domain model.
We wrote some scenario files with .osc file extensions and each passed the test.
Please read README_OpenSCENARIO_2.0.md for more details.

Where has this been tested?

• Platform(s): Ubuntu 20.04
• Python version(s): 3.8.10
• Unreal Engine version(s): UE4
• CARLA version: 0.9.13

Possible Drawbacks

The support for the domain model is not complete, but some simple scenarios can already be implemented, such as the. osc file example in the example folder.

Hey, thanks for the amazing PR. This is definitely a huge contribution to the repo.

Overall, this looks like a pretty good addition to the repository, and while there might be some sections that can be improved, they can definitely be done in subsequent PRs without any issues. This is also a self-contained feature, so even if some errors appear, they won't affect other areas of the repo.

Again, thank you very much for all the effort, and the willingness to share it with us!
