Allow creating deck via #deck:... if non-existent when importing (#4154)

* add deck name field to metadata protobuf msg

* fallback to creating new deck specified in `#deck:...`

* update tests

* create deck if it doesn't exist

* plumbing

* allow creating deck via `#deck:...`

* apply suggestion for protobuf
