Add method or log message to find the model log file

When you start a model (e.g. pcrglobwb), it can take some time where it might seem like the kernel is hanging. In the meantime, model log messages are printed in the model working directory. It might be useful to add a console message like
`f"Initializing model. Log messages will be written to {cfg_dir}/default.log` or something like that.

Can this be added as a (model-specific) method to the model class?
