feature: add scenario?

[qqkkwan]

Any plans about adding OpenScenario? like playing Scenarios according to the .xodr and .xosc files and make web animation.

This would fit well together with #8 . I have more time to work on this project soon and will check it out.

esmini https://github.com/esmini/esmini is a good example, which is referenced a lot in OpenScenario documentation
