Add the set of record level licences to DOI metadata, and display in doi-service

[adam-collins]

• In the same way as data resource, provider, etc is collected for each occurrence download, collect the record level licence information and add to the DOI metadata.
• DOI occurrence download pages https://doi-test.ala.org.au/doi/bf86c17c-ac46-49da-b2c9-c993e762cda8 list licence information above the data resource/licence table. This should be replaced witih the record level licence set for new downloads.
