Add print() option

[AaronDMarasco]

Allows a user-defined string (or callback function) to prefix every output when using the pretty() call.

Interesting. Thanks for making the PR. I rarely use the print function but it seems you are using it extensively that you want to add a prefix.
Do you think the fstring overhead is that much? If yes, please go ahead with your suggestion. Compared to a lot of other parts of the code that we should optimize, I don't think the f-string's overhead is that much.

I'd say just take as-is then.

Our use case is that we ship a config file and then let the user write one that overrides. Then we dump the diff of the config data structure to the logs, so when they have issues we can see in the logs what may have been a dangerous change.

LGTM!

Thanks; I'll read into that more later this week.
