Derivatives API Java Client Role Enums #50

Ticket raised from StackOverflow question (https://stackoverflow.com/questions/66137061/derivatives-api-java-client-role-enums)

There are currently issues when calling /modelderivative/v2/designdata/{urn}/metadata during a PDF upload.
The request object cannot be mapped into the Manifest response due to errors with unknown enums being returned for ManifestChildren.RoleEnum Manifest -> ManifestDerivative -> ManifestChildren -> RoleEnum

I have been able to work around this issue with a local jar build by adding the four missing enums

• leaflet
• leaflet-zip
• pdf-strings
• pdf-page
