Fix plot_phantom_map for dynamic phantoms

[pvillacorta]

This should solve #407, although we are also getting rid of the play/pause buttons.

This PR:

• Gets rid of the dispatch between static and dynamic phantoms when plotting
• Sets max_spins keyarg default value to 20_000
• Uses scattergl when view_2d is active
• Removes the play/pause buttons
