Added callbacks to ArchiveFile.Extract and Entry.Extract for progress events.

[runemoennike]

The IArchiveExtractCallback contains SetTotal and SetCompleted which are called at various points during file extraction. These points differ between file formats, but along with GetStream some form of progress reporting is possible, which is what this commit introduces.

The Extract methods on ArchiveFile and Entry now accept an event handler that will be called with the new ArchiveExtractionProgressEventArgs and EntryExtractionProgressEventArgs, respectively, as the extraction progresses. Please note that it is very inconsistent when this is invoked, depending on the format. However, it is guaranteed to be called at least at the beginning and end of extracting each file.

@SalmaBegumJSR you have to clone my fork of the repo, and switch to branch 55. If you do it from a terminal/console, it looks like this:

git clone https://github.com/runemoennike/SevenZipExtractor
cd SevenZipExtractor
git checkout 55
