Modify existing field to allow for the saving of image data(URL and metadata) directly to the content table

• Must be retrievable via GraphQL query on entries
• Must have an accompanying column in the content table to store the Canto asset ID for easy lookup/metadata modification

As per our conversation, what we'll do is create a totally new field type for this, to ease the migration from the old to the new schema/field type

This is the bulk of the work:

• A field that returns a Collection that can be searched/filtered through
• A field-based GraphQL API that allows fetching said Canto asset(s) via regular Craft queries
• A GraphQL API that allows for searching through all of the DAM Asset Picker fields by creating a Collection of all of their data, and then exposing all of the Collection methods via a dynamically generated GraphQL API using PHP Reflection methods on the Collection class
