How to set the name of the worker?

# Issues
Thank you very much for your work. I am using dramatiq_dashboard，it is very good,but it is very difficult to understand that worker name is a bunch of meaningless letters.

As we know, there will always be an accident. However I don't know what I can do at that time. Can you tell me how to set name of worker and which tasks each worker is running?

Thank you.
