Workflows: missing orcid in parsing

[ErnestaP]

Need to extend IOP, OUP, Elsevier and Hindawi parsers: add orcid parsing from the author.

It does exist in old scoap3 parsing: https://github.com/SCOAP3/hepcrawl/blob/master/hepcrawl/extractors/s3_elsevier_parser.py#L141

But does not in Airflow workflows for:

• Hindawi (already implemented)
• Springer (already implemented)
• IOP (Couldn't find any of the examples)
• APS (Couldn't find any of the examples)
• OUP
• Elsevier

Each of the publishers have individual path to authors' orcid's.
Wanted result:

authors": [
    {
      "first_name": "first_name",
      "last_name": "last_name",
      "orcid": "orcid",
      "affiliations": [
        {
          "value": "value",
          "organization": "organization",
          "country": {
            "code": "code",
            "name": "name"
          }
        },
