Add ?as=iiif param to top level collections endpoint.

[mathewjordan]

This work adds a ?as=iiif param to create a IIIF resource for the top level collection of collections. In the process, we have also extended out Presentation API properties across all collections.

To review, navigate to the your dev API endpoint, ex:
https://mat.dev.rdc.library.northwestern.edu:3002/collections?as=iiif

If you really wanna see these Collections in action, check it out in:

• This top collection should be a IIIF resource with the type Collection and have a list of Collections under items.
• requiredStatement, seeAlso, provider, logo, and homepage should be present in this collection
• Individual Collections should output as before, ex: https://mat.dev.rdc.library.northwestern.edu:3002/collections/3e38c22d-de6e-4827-9097-96d0da968746?as=iiif
• Search result Collections should output as before, ex: https://mat.dev.rdc.library.northwestern.edu:3002/search?as=iiif&collectionLabel=Pug&collectionSummary=1+result&query=pug

This looks great. The only thing missing is an update to the OpenAPI spec – the /collections route spec needs a reference to the as param (which you can just copy/paste from the /collections/{id} route spec).

I don't think there's anything to update in the docs regarding the Presentation API stuff because we pretty much punted and called all document responses object types.

Looks good. Collections search route (/search/collections?as=iiif) working as expected as well with POST body.

Thanks, updated the spec!
