Subject: [PATCH] Add Depth to Commands.Fetch

Thanks to https://github.com/libgit2/libgit2sharp/pull/2070, it is now possible to Clone with shallow depth. In some cases you'd want to unshallow. The current workaround is to delete the local repo and re-Clone with full depth. To avoid this un-necessary step, the Depth could be respected by Fetch, the same way it is doing it for Clone.

This patch works for the cases I tested (don't forget to check `repo.Info.IsShallow`), but it seems too simple and I don't know what would be required to test and implement it properly. So I'd like to ask for help on this, thanks.
