Update Europeana to collect image dimensions

[stacimc]

Problem

We'd like to make sure that all of our image provider scripts are collecting data about image dimensions.

Description

The Europeana script does not currently do so, but the information is available in the API via the single record endpoint. We should update the provider script to collect this info.

There is precedent for making an additional API request per record, notably Flickr but also some others like Metropolitan and NYPL. That being said we should make sure that adding it here doesn't have any dramatic effect on performance.

Additional context/dependent PRs

Note that Europeana is currently turned off in production, because turning it on will initiate a backfill. We should wait for WordPress/openverse-catalog#644 to make sure that we can omit the DAG from Slack notifications, to prevent flooding the channel. <- This has been merged.

We also have an issue to update Europeana to use the new API endpoint, and update any necessary fields: #1727. It may be helpful or even necessary to do this work first. <- WordPress/openverse-catalog#974 has been merged.

Implementation

• 🙋 I would be interested in implementing this feature.

Adding here that Europeana script also needs to collect file type and file size information.

Given Europeana DAG hasn't been activated yet this is probably more dependent on updating the API endpoint, so I'll move it to the Provider DAG stability milestone.

Since this ticket is specifically just for populating image dimensions, I think this should be in the Data normalization milestone. @krysal I see you moved it out of that milestone -- would you object to moving it back? We have other changes to Europeana (#109) in Stabilization.

[krysal]

It's okay! I moved it to out of the Data Normalization milestone because it is not an active DAG and thought it was going to be fixed after the milestone. So if it gets fixed before then it makes sense to (re)include it 👍
