Show information about latest state of feature

[planemad]

When one is inspecting a bad change, it is very helpful to know if the feature had been later modified/corrected by another user. This helps a reviewer take appropriate action if needed.

Current workflow

https://osmlab.github.io/changeset-map/#48202080

To find out if this feature has been deleted, the user currently needs to check the OSM object page https://www.openstreetmap.org/way/489873496/history

Expected workflow

On clicking the feature in changeset-map, indicate if a newer version of the object exists or has been deleted. This will allow the user to jump to inspect the latest changeset involving this feature or know that the issue is resolved without needed to check an external site. This saves considerable time when cycling through various features of a changeset.

Mediawiki watchlist does this by showing if the change is part of the current state of the page.

Thanks for the ticket @planemad .

I imagine we would do this by querying some API for the feature id that would let us know if there were further edits made to it.

Let's explore possibilities.
