Add plot-ts utility

[lispandfound]

This adds the plot-ts utility back to visualisation. I originally rewrote the ancient gmt-based plot-ts added it to workflow. Now, however, I realise it is more appropriately placed here because it is not a scientific computation. I had to rewrite it (again!) because the 3D-visualisation based on PyVista was too janky to work properly with all the cartographic features you actually want. Instead the actual video is generated using simple matplotlib animations with cartopy (rather than GMT) forming the geographic backend. Eventually I would prefer to use cartopy over GMT in the entire codebase.

I have opted not to test the plot_ts module for two reasons,

1. The utility is rarely used, and only for communication and sanity checking purposes, and
2. It is slow and it would be extremely hard to check its output.

I have omitted it from code coverage

• Using set_array to update pcolormesh may not update the RGBA data correctly with shading='gouraud'. Consider using set_facecolor to update the quadmesh's facecolors for clarity.

pcm.set_array(apply_cmap_with_alpha(current_data, 0, max_motion, cmap=cmap))

• The new production code in visualisation/plot_ts.py is currently excluded from test coverage. Consider adding tests for this utility instead of omitting it.

Despite saying I wouldn't, I've multi-processed this module. It provides a modest (2x) speedup on my computer. Have also added:

1. Zoom controls because some simulations need to be zoomed in from their domain.
2. OpenStreetMap tile support. If enabled, it uses tiles from OpenStreetMap instead of simple line drawing of the coast. Mostly useful for public communication purposes.

The multiprocessing somewhat complicated the logic. It now resembles something like the old plot-ts but it reliably works and provides time-to-completion estimates.

As long as Numpydoc and Ruff are happy, I'm happy to approve
