Evaluate using runtime.CallersFrames internally. #10

Closed ChrisHines closed 7 years ago

runtime.CallersFrames was added in Go 1.7. Using it could clean up some of the internals of this package and eliminate the need for the findSigpanic function.

So, having submitted a PR for this, I can say it definitely does clean up a lot of the internal stack navigation logic but it seems to come with a decently heavy performance hit. Granted, stack generation is not really a thing that most applications are going to be doing at a high frequency but for things like logging frameworks, that may be a bit of a big deal.

There could also simply be inefficiencies in my code, so if anyone can give it a look over, perhaps that will shave off some time. The fact that this method performs far more allocations than the previous method is unavoidable, however.

Thanks for giving this a shot. I'll review your PR soon.
