If it's possible to add a callback function so that can be show now extracting file in progress

[Muska-Ami]

Like the title, we need a callback function when extracting files to disk:

extractFileToDisk(File file, Directory dir, Function callback);

i am going to second this! i would like to see convenience functions for both extraction and archive creation that would provide callbacks, so we can show progress to the end user.

I added that callback to the 4.0 branch I've been working on. https://github.com/brendan-duncan/archive/tree/4.0. Hopefully it will be ready soon.
