feat: Add Order of Performed Nodes

[sandorstormen]

Changes performed_nodes to immutable ordered sequence.

Would adding temporal info (e.g. timestep or similar) to the compromised attack steps not be a more general solution, in case the order or temporal location of the events are of interest?

Sure, but this is just a quick fix (because it would be nice for me). We can work in absolute temporality later.

Looks good. Only problem I have is that the method node_is_compromised will go from finding a node in a set to finding a node in a tuple which means much worse performance. That function is not used internally so it doesn't affect performance in the simulator, but it could be used every step by some of the wrappers/interfaces.

Closing as we chose a different approach #240
