Extract authors as split firstname, lastname, others where possible

[blahah]

If the source provides access to structured author names, include them

"author": {
  "name": "Bob G Dylan",
  "firstname": "Bob",
  "lastname": "Dylan",
  "others": "G",
  "email": "[email protected]",
  "institution": ""
}

The main point is that scraper should extract data in the most raw form available from the source and not try to concatenate/combine/process data. This should be done at later stages (where you might have more information available, like all known authors in the database against which you could cross-check).
