datacite: adding datacite-specific extra metadata

* attributes.metadataVersion
* attributes.schemaVersion
* attributes.version (source dependent values, follows suggestions in
https://schema.datacite.org/meta/kernel-4.3/doc/DataCite-MetadataKernel_v4.3.pdf#page=26,
but values vary)

Furthermore:

* attributes.types.resourceTypeGeneral
* attributes.types.resourceType
