Show button for shop manager to duplicate orders

Hey, very useful plugin, thank you.

As a shop manager/admin, I’d like to be able to duplicate orders. e.g. if a customer’s order goes missing or is sent with the wrong items, we create a new order for them in the backend, set it to $0, processing, and send it.

So I’d like a button in WooCommerce admin single order UI to duplicate the order with a pending status. The note referencing the original order is very useful.

If you put this plugin on GitHub I might be able to implement it myself and send a PR.
