Abort a zipping process.

[mdeangelo-CT]

Expected behavior

Create a method to abort zipping in FastZip. As seen in issue #373, we see that it is unsafe to abort a running thread. Could we implement a method that could safely abort the zipping process?

You can use the ZipFile.CompletedFileHandler event and cancel the compression there if you want, something like:

var fastZip = new FastZip(new FastZipEvents() {
    CompletedFile = (_, args) => { 
        args.ContinueRunning = !aborted;
    }
});

fastZip.CreateZip(zipFileName, sourceFolderPath, true, "");

Not that this is single threaded, so if you want to listen for some kind of external event you probably have to do threading and sync/lock
