added plots on map with plotly

[figuetbe]

This merge request adds support for plotting Flight and Traffic objects on a Mapbox layer using the Plotly.
With these features, you can create interactive maps that display flight trajectories, altitude, speed, etc.
Additionally, these methods enable the creation of animated plots, allowing you to visualize trajectories vs time for example.

Thanks @figuetbe

Would be nice to have in addition:

• some visualisation with comets for trajectories when plotting animation;
• something similar to plot_time() and chart() for plotly when plotting other features (not only maps)
