Implement unrelated returns #435
Description
What problem does this feature solve?
Currently, it is only possible to create a related return based on a pre-existing consignment. When you look in the API Reference you find that unrelated returns are also easily possible. As said by the docs, this is useful for for example repair services.
It would be nice if the unrelated returns API was built into the sdk so that these things can also be done.
What should the solution look like?
It should be possible to use the ConsignmentFactory to create a return shipment.
