[Normalization] Fix and link the `funding.identifer` entries using NIH RePORTER API

[flaneuse]

People fill out funding.identifier in all sorts of weird wacky formats. Clean up the:

• funding.identifier format
• funding.funder.name
• link to funding.url
• add funding.name
• add funding.description
• add funding categories (see https://github.com/NIAID-Data-Ecosystem/nde-portal/issues/4)
• add funding.keywords
• maybe add funding.creator/author? (PI / Project leader)
• maybe add funding.creator.affiliation?
• maybe add FOA? (funding.isBasedOn?)
• maybe add project start/end date?
• maybe add Program Official? (funding.funder.employee?)

using the NIH RePORTER API

Note that there are a number of records with funding info that consists only of funding.funder.name. These records will not be normalized via the funding.identifier.

Normalize all funding.funder to the crossref funder registry, using funding.funder.identifier so that a search for one funding.funder.name will be able to pull all records funded by the same funder (regardless of how the funding.funder.name was originally entered)
