Describe the solution you'd like
A (or multiple fields) that allow to link to the official page and/or reading service for the issue. For example, a comic entry for "Amazing Fantasy 15" could have a field "publisherPage": "https://www.marvel.com/comics/issue/16926/amazing_fantasy_1962_15" and a button in the UI [Publisher Page] that opens the link and an additional field "publisherOnlineReadLink": "https://marvel.smart.link/fiir7ec77?type=issue&drn=drn:src:marvel:unison::prod:092dd587-22fb-4402-a7e9-66116273092f&sourceId=16926" which shows in the UI as a button [Read Online].

Additional context
This could be useful to instantly reference the official page when researching comic using this database or even quickly start reading said comic if available in the publishers official reading service, or even see if said comic is even available in the official reading service.

For API consumers this could also be useful if they want to include a link to the official page of the publisher, load some more data from the official publishers page or enable automatically opening the official reading service (a reading order page/service would come to mind)
