fix: update requirements for adsputils and requests

Modified PNAS parsing

PNAS previously had feedparsing and request/fetching built into the parser. Those have been removed, and you now pass PNASParser the raw contents of a file rather than a URL to fetch. This separates the Harvest and Parsing components of the parser.

Modified IOP, ProQuest

• IOP Parser changed to conform to new JATS delivery; old files can be read by calling parser.parse with the argument (parser='lxml')
• Set default ProQuest collection to 'GEN', and remove 'GEN' if more than one collection is present
• Cleanup of several tests
