Feature Request: add support for wandering traders

[NousadS]

Just as I know, nowhere in ponders or examples is it said that you can trade with wandering traders. It would be cool to see it.

I think I just have thought about this in dev, but since Wandering traders don't restock or stay around it wouldn't work much to have to change the wandering trader's AI, and the wandering trader doesn't have any good trades anyways,
Thanks for the request though, I'll keep it in mind potentially for a future update
