Allow specifying unpacked directory location

[hawkins]

I am packaging an application in Electron and using asar to do this. My application has a cfg folder that end users are allowed to edit to change core behavior of my application. I've specified all files in the cfg folder to remain unpacked, but this means users would navigate to resources/app.asar.unpacked/cfg instead of just cfg from the root level of the installation to make their changes.

It would be nice if there was a means by which to specify where unpacked files for asar are stored. Something like the following, maybe:

asar.createPackageWithOptions(appDir, buildDir, {"unpack": "*/cfg/*", "unpackedDirectory": "../"}, function () {
        ...
    });
