Implement Tokens for quick access to Archipelago Specific data

[DiegoPino]

What?

The time has come and we have the perfect skillful candidate to work on this (👀 @pcambra !) Tokens. There is SBF and Archipelago Specific data that can be exposed as Drupal [tokens] to the Drupal Ecosystem. This issue will just open the door to those and mention the most basic ones:

• IIIF servers
• A particular JSON key/value of a SBF field (requires flattening special characters because tokens use : as separators and JSON keys can contain those
• Direct access to as:images, as:documents Drupal IDs, URLS, etc and also via drop_field as a generic list.
• Active View Mode for an ADO
• Parent ADOs (via our computed field or via a particular key like ismemberof)
• Strawberry flavor document count for a given ADO, and for a given ADO/File Match

These are the ones I can see right now may be useful and I would focus on a first pass only on the ones marked in bold because the second one can really give us already a lot of flexibility

I like how webforms uses Tokens so a good way of integrating this also in our Twig Templates.

@pcambra more ideas? What do you think?

@DiegoPino That would be great! If I'm right, token can be also used in Views Twig rewrite, right? Thanks for this @pcambra
