Progress event

I already tried, and I can unzip LZMA2 files without problem. But how can I have a Progress?

We currently use the getOutputPath callback to show some sort of progress, but since actual exctraction happens after these callbacks, it's not very accurate.

@adoconnection do you know of a way to get progress from the underlying .dll? Then I'd be happy to implement it in here.

@runemoennike Hi! Unfortunately I dont know

@adoconnection @jorensanbar I've given it a shot here, where I've added optional callbacks to Extract() on Entry and ArchiveFile. However, my new unit tests are currently failing for everything but the 7zip format :( It seems the SetCompleted and SetTotal on IArchiveExtractCallback are not called consistently across formats.

@adoconnection I managed to standardize so the callback is invoked at least at the beginning and end of each extracted file, so I've created this PR: #60
