Updating manifest generation to use IIIF 3.0 Presentation

[Dananji]

Description

Avalon generates IIIF manifest for each media object. This is performed on the fly when you visit media_object_url/manifest. And this manifest generation seems to be partially using the presentation API 2 (v 3.0 changelog).
We also have the timeliner in avalon currently using a IIIF manifest for rendering of the component, but this might be different from what is mentioned above. As per the notes below there are 2 code segments in media_objects_controller and timelines_controller for handling manifests.

IIIF manifests in avalon needs to be fully updated to use Presentation 3.0.
Validator for Prezi 3 compliance: https://iiif.io/api/presentation/validator/service/

Notes

• Code for manifest handling for media object: https://github.com/avalonmediasystem/avalon/blob/develop/app/controllers/media_objects_controller.rb#L465-L484
• Code for manifest handling in timeliner: https://github.com/avalonmediasystem/avalon/blob/develop/app/controllers/timelines_controller.rb#L196-L203
• A sample manifest in Avalon: https://spruce.dlib.indiana.edu/media_objects/474299231/manifest
• Maria's thoughts;

I looked at the rest of one of the manifests and think that the "service" is probably the problem for validators to accept our manifests. If you have a way to try one of MCO's manifests excluding the service elements and the @ from @none, we may actually find that this is all...

I used a IIIF manifest from MCO in the IIIF validator without service and @ from @none tags as @mcwhitaker suggested. And found the following issues that needs to be fixed;

1. Annotation requires an id property
2. Cannot have null values for properties. Ones that I came across when testing are, label, value in metadata, height, width. Instead of null values use { "none": [] }.
3. homepage property accepts an array
4. for UV support add format property for resources

Manifest tested: https://gist.github.com/Dananji/ecd53e3a3d802e62b07c8c1c794a2210, to test this in the validator, I put this on maple here.
Changes from above made to make it valid: https://gist.github.com/Dananji/ecd53e3a3d802e62b07c8c1c794a2210/revisions?diff=unified
