apply, but preserve feature values

[asinghvi17]

It would be useful to have an apply_as_feature function, which acts just like apply, but passes geometries to f as Feature objects, that have all the attributes of the parent feature. This would help with analyses where the user is trying to compute something on a feature collection.

This doesnt just work with apply and a FeatureTrait target? It should...

(Or maybe I dont understand the idea...)

[asinghvi17]

The idea would be that apply_as_feature(f, geom, PolygonTrait()) actually does the decomposition from e.g. geometrycollection or multipolygon to polygon, but wraps that polygon in a GI.Feature.

And the properties are passed down from the parent? So grab a feature on the way down the rewrap with it when we hit the target?

Yep! I was experimenting with area to area interpolation and it struck me that this kind of thing could be useful.
