Parameterize the Renderer trait over GenericSim to avoid taking it dynamically

Notably, this allows the SerializerRenderer to serialize the actual
state to disk, as-is. That'll allow for more compact images, and
potentially also a way to resume simulations.

I expect the viewer will be broken for new simulations, initially.
