[TD] Move navigation queries outside DynamicRender class

[Agustin Alba Chicar]

Towards a better encapsulation of the functionality, we need to make the following splits:

1. Create a Builder class that constructs a RoadMap from the RNDF information.
2. Refactor mesh / markers code to consume the RoadMap and outside the builder (currently inside DynamicRender).
3. Create a class that handles queries to the RoadMap to navigate it.
