introduce no-access badge to indicate known DwC-A registration but non accessible content

[jhpoelen]

inspired by https://discourse.gbif.org/t/assessing-fairness-of-biodiversity-data-through-badges-and-download-buttons/4246/6 , in which a dataset was registered with GBIF, but their DwC-A endpoint URL was not accessible to retrieve the content.

Previously, "FAIR" and "unknown" badges were produced.

Suggested is to produce "FAIR", "no access" and "unknown" DwC-A badges.

"FAIR" - content associated with provided identifier is findable (via GBIF/iDigBio), accessible (via registered endpoint), interoperable (by using DwC-A) and re-usable (can be moved and redirected to).

"no access" - content associated with provided identifier is findable (via GBIF/iDigBio), but could not be accessed via the registered endpoint.

"unknown" - provided identifier has unknown associations with desired content (e.g., DwC-A) in the current provenance graph.

a first version of a no-access badge was introduced via v0.7.16

for example, see attached

Also note that the http response header contains provenance information on the requested resource, even if the associated content would not be accessed.
