Send box sizes in order email for UPS and USPS shipping
Since the UPS and USPS extensions use box sizes to calculate shipping rates; send the box sizes in the order email to the admin so the employees that do the packaging can use the most efficient boxes.

While it's great that the Box Packer method calculates product sizes and selects the best box size for us, it's equally important that the order form (in email and in Woocommerce) display those box sizes to fulfill the order. Without the box size, it's all a guessing game.
