Rename the `setup_file` parameter in `run_experiment()`

Argument naming consistency

In run_experiment(), the argument name setup_file for the experiment definition file is somewhat confusing.
I would suggest either:

• using experiment_file, or
• consistently using file (as in other functions like inspect_experiment(file)) to improve API consistency.

Thanks for the suggestion! In this case, I find it better to keep setup-file, since it matches the NetLogo API flag.

--setup-file <path>: read experiment setups from this file instead of the model file
