Add heuristic to enable --slow for ZK chains

[Karrq]

The only way to run it without --slow would be to use a chain id that is detected as not having batching support, but that's a rather limited list, and not really a solution imo.
We may consider improving this in the future but right now there's no such work being done

ZK chains do not support batching, therefore scripts which have transactions that depend on each other will fail when broadcasted (as simulation is always sequential).
Perhaps there's another way to detect if a chain is ZK or not (similar to how we do for fork perhaps?) and use that information to enable sequential broadcasting
