Handle decamels the function name about err2

Thanks for your response and continued development on this!

Hello,

Thank you so much for the kind words and the feedback! Highly appreciate.

My first thought about your request is that I need to do something about that 👍

This was the first implementation to get more information about the subject. During the first implementation, I noticed those marginal cases like anonymous functions (.Func1) and how to treat the actual package name (uuid.New() -> "uuid new" is better than just "new", but not always!). Our use cases are covered by simple decameling because we rely on logs for err2's error trace functionality and assertations. But yes, I'll look for the next-best solution and hopefully a simple API.

My gut feeling is that I'll bring a formatter interface and a few default implementations like decamel and noop. I will cover this in the next release.

Once again, thanks for the feedback!

FYI PR #11 now fixes the decamel bugs. I'll think I will release it quite soon, but before that, I am trying to think of a new config API where err2 callers could bring their own formatters as well. Letting you know..

There is now a new version, v0.8.13. Please check it out.

I'm preparing to close this issue. Here's an additional example of how to implement and set your own Formatter:

	err2.SetFormatter(&formatter.Formatter{
		DoFmt: func(raw string) string {
			return "my ERROR: " + raw
		},
	})

Anybody please let me know if you find any bugs or annoying things in the formatted API. Thanks!

Thanks for the update! Will let you know if anything else comes up :D

The new API and fix are working. Fixing the issue.
