Test SolaraViz in CI

[EwoutH]

Initial attempt at testing the visualisation in CI.

@rht I can't get the imports working properly. I tried a lot of things, but somehow it always end up with one or more import errors. I know you're good at this, could you take a look?

Sorry pushed the wrong version, this is my attempt that got closest. It currently fails on imports in the models:

    import networkx as nx
    import solara
>   from aco_tsp.model import AcoTspModel, TSPGraph
E   ModuleNotFoundError: No module named 'aco_tsp'

    from mesa.visualization import SolaraViz, make_plot_measure
>   from model import GameOfLifeModel
E   ModuleNotFoundError: No module named 'model'
