zip support

[MichaRotstein]

Can we have support for zip files ?

I don't see why not, it's simple enough to create ZIP files:

using (ZipArchive archive = ZipFile.Open(targetPath, ZipArchiveMode.Create))
{
    archive.CreateEntryFromFile(path, Path.GetFileName(path), this.compressionLevel);
}

I need to put some thought into how best to expose this new option for the user, and how to organise ArchiveHooks in include it.

Can we expect this feature in the foreseeable future? If not, will I get a review if I try to build this feature myself and create a pull request?

@opheoHeidrich I don't have much time these days, so it's not coming from me any time soon 😞 - would be happy to accept a contribution from yourself tho!

A simple way to expose this option is just to add a couple of new ArchiveHooks ctors that include a new enum parameter (of type CompressionType or whatever). Then have the original 2 ctors just direct to the new ones, setting the new argument to CompressionType.Gzip.

The new ctors would be Something like:

public ArchiveHooks(CompressionType = CompressionType.Gzip, CompressionLevel compressionLevel = CompressionLevel.Fastest, string targetDirectory = null)
{
  // TODO: implement
}

public ArchiveHooks(int retainedFileCountLimit, CompressionLevel compressionLevel = CompressionLevel.Fastest, string targetDirectory = null)
{
  // TODO: implement
}

Obviously the On* event handlers need to be updated too. Unsure off the top of my head about CompressionLevel with ZipArchive; it might need to be mapped to some other values. So, a simple approach - what do you think?
