Support Hazmat Shipments

Allow for selecting that a shipment is hazmat. With the US, the postal service has updated their system and like to have labels indicate an “H” for Hazmat instead of the typical “G” for ground or “P” for priority. Rollo does not provide for the ability to mark a shipment as hazardous and this sets you back from the competition. Pirate Ship even allows this, along with Amazon, eBay, and so on.
