1. use ES search_after instead of page for next links
2. Removes prev links (not possible to do easily with search_after)

I'm seeing the deep paging issue on https://landsatlook.usgs.gov/stac-server (e.g. https://landsatlook.usgs.gov/stac-server/collections/landsat-c2l3-ba/items?collections[]=%5B%22landsat-c2l3-ba%22%5D&page=41&limit=250).

I know this is the wrong place to ask, but does anybody know who maintains the LandsatLook STAC API? It would be great if it could be updated to stac-server@0.4.0. I'll give https://answers.usgs.gov/ a try too.

We're running into the same 10000-limit issue with the landsatlook stac server. @tschaub did you ever try to contact them about this and got a reply?

Response from custerv@usgs.gov on 2022/05/31:

The USGS is on a one year rotating schedule for updating our STAC versioning. We have an update coming shortly, but we cannot keep up to date on all version releases as we have a very involved/ in depth check out process to vet any new updates.

Thanks for your understanding.
