Determining when parsing is complete.

[brentrager]

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch barhandles@0.5.4 for the project I'm working on.

I was looking for a way to know when a call to extract had come to an end.

Here is the diff that solved my problem. This results in a callback with an empty path array to indicate the end has been reached.
