Add a callback to onEntry that can be used to continue or cancel extraction

[mikebq]

I have a need to inspect the contents of an archive and verify that it contains only certain file types.
I can supply an onEntry function in the options passed into extract to inspect the entry and check if it is allowed or not. However I do not see a way to signal back to extract-zip whether the extraction should continue or be cancelled. Ideally I want to use a library such as mmmagic to do deeper inspection where the result is returned in a callback.
It would be very useful if onEntry took a third parameter, a function, that could be called to continue/cancel the extraction.

I have a PR with tests and documentation updates for this here: #69

I got stumbled upon here for a similar use case. Is there any plan to make this feature upstream?

I also have a similar use case. I'm currently extracting and deleting certain files/folders, but if extract-zip provides the support for skip extraction, the script will be simpler.
