Use new Discrete Event Scheduling in examples

[EwoutH]

Open for contributions!

Now that the Discrete Event Scheduler (DEVS) is released as experimental in Mesa 2.3.0, it would be interesting if we can use it in examples.

• Current code implementation: mesa/experimental/devs
• Original PR: support for discrete event scheduling mesa#2066
• Original discussion: Hybrid ABM DEVS with MESA mesa#2032

All three mesa benchmark models already use devs, so those changes could be ported over.

The approach for this would generally be:

• Read up on DEVS
• Go through the Mesa examples and seek opportunities where the DEVS could simplify or improve things.
• Open a Discussion on mesa-examples proposing your changes
• Implement them and open a PR here

The nuance here being that applying the DEVS is not a goal to be implemented as much as possible, but a means that could make some model (parts) more elegant, efficient, readable and/or performant.

Bringing over and documenting the wolf_sheep benchmark model could be a good start.
