Can you explain the removal of all the files in modules/editable-layers/src/lib/ and the curve-utils? Are they not used anywhere else across the repo or exported? (cc. @ibgreen, @georgioskarnas)

From the original PR (I should copy the description across ):

Drops code from long, long dead lib folder, and an unused curve-utils file, rather than trying to update turf usages there

A bunch of stuff from lib was exported (see the removals in index.ts), but none of it is relied on in the rest of the package, or referred to anywhere in the repo or the old nebula.gl documentation. As far as I can tell, it's all dead.

Im seeing a TON of FeatureCollection<SingleGeometry> instances, this would be better as a shorthanded, single export util coming from the same file these types are defined. Cleans up dependent files with a single export rather than two. Open to just about any name that is a shorthand of this.

Swapped for GeometryFeatureCollection. There's some additional cleanup that could be done across the repo to point Feature & FeatureCollection imports directly to geojson, but I tried to keep this PR focused on the actual change as much as possible, so I'd suggest we just follow up.

Excellent. Thank you for your time. Gonna pull a senior collaborator in here for a final check, and once they confirm, we'll see this finally land.

I think I've addressed all the comments above. There's a lot of noise in the commit history now, so I'd suggest we squash.

Incredible work. Squash and merge is default. Thanks for getting to this so quickly.
