We already have a bunch of examples in the repository that link to repositories that are external to this one and maintained by us. This works well enough but we should have room for user provided examples & resources, like the OpenMVG Python example.

For this we should iterate on our example sections on https://www.rerun.io/examples and probably figure a way out that doesn't require folders with readmes in the repo here. A single more centralized location would make more sense as we hope that those external examples will outnumber all others in the future.
