Add missing actions to gym environment

[duyminh1998]

When we migrated from Typescript to Python, some important functions (e.g. moving an aircraft) were dropped because they were always tied to the frontend. We need to add these back in to make it possible for agents to better interact with the gym environment.

As a proof of concept, make a demo script that shows a scripted agent guiding an aircraft from point A to point B.
