Canvas Panel heavy payload

[sammeltassen]

Sometimes Canvas Panel seems to load more resources than necessary. This page for example loads 50MB of resources:

• https://deploy-preview-26--heritage-tudelft.netlify.app/nl/objects/trg-9809-e-03

The same manifests loads 2.4MB of resources in Mirador:

• https://projectmirador.org/embed/?manifest=https%3A%2F%2Fdeploy-preview-26--delft-iiif.netlify.app%2Fmanifests%2Ftrg-9809-e-03%2Fmanifest.json%3Fmanifest

@stephenwf shared the following sources from the atlas-viewer library that Canvas Panel uses:

• https://github.com/atlas-viewer/atlas/blob/main/src/spacial-content/composite-resource.ts#L130-L181
• https://github.com/atlas-viewer/atlas/blob/main/src/clean-objects/traits/composite.ts#L86-L106

Hopefully just tweaking some configuration and updating some dependencies.

@sammeltassen can you confirm that it doesn't load as much resources in Theseus for you?

@stephenwf Theseus seems fine! So yes indeed it's probably just that
