Import Placeholder from CSV allows "AssignToUser" based on Username.

I would like the API to allow the same feature. I need to be able to assign an owner of an iPad via the API by PUT "username".

Currently, the API only allows assigning owners to devices using a Jamf School ID assigned to the user (sort of like a JSS ID). This requires acquiring the Jamf School ID for the user in order to assign the user to a device.
