Include funding information in PublishedData

At DESY, one discussion point has been on identifying the funding source underpinning the creation of the data. Moreover, acknowledging funding is likely a common requirement.

The DataCite metadata schema (current v4.6) defines FundingReference to allow a DOI to capture this information.

This issue requests that SciCat adds support for acknowledging funding when minting a DOI. The suggestion is that SciCat follows the DataCite metadata schema when deciding on the MongoDB schema to support this.

The following is an example, taken from the DataCite metadata schema:

"fundingReferences": [
  {
    "awardUri": "https://cordis.europa.eu/project/rcn/100180_en.html",
    "awardTitle": "MOTivational strength of ecosystem services and alternative ways to express the value of BIOdiversity",
    "funderName": "European Commission",
    "awardNumber": "282625",
    "funderIdentifier": "https://doi.org/10.13039/501100000780",
    "funderIdentifierType": "Crossref Funder ID"
  },
  {
    "awardUri": "https://cordis.europa.eu/project/rcn/100603_en.html",
    "awardTitle": "Institutionalizing global genetic-resource commons. Global Strategies for accessing and using essential public knowledge assets in the life sciences",
    "funderName": "European Commission",
    "awardNumber": "284382",
    "funderIdentifier": "https://doi.org/10.13039/501100000780",
    "funderIdentifierType": "Crossref Funder ID"
  }
]

Please note that "Crossref Funder ID" is now deprecated in favour of using ROR.

Start by tracing PublishedData and the DOI-minting flow in the backend, then compare the required fields with DataCite metadata schema v4.6 FundingReference. Define how fundingReferences should be represented in MongoDB and included when minting a DOI. Done means SciCat accepts and preserves the funding information and emits it in the DOI metadata.
