Add deletion

[KTibow]

I know it's usually a bad idea to add the ability to delete, because then ransomware might erupt, but I'm using this library to do backups and I want to delete the old ones to not let them fill up my OneDrive. Is there any way to do this?

What happens if I try to overwrite something?

Found it. You call .delete() on a client.item(). But can you please add better docs?
