Feature request: iterate over flattened features

See original GitHub issue

Turf has a flatten method that creates a feature collection. It would be helpful to have a flattenEach method that traverses them with a callback without allocating them and consuming memory. I can submit a PR if there is interest in this feature.

Note, this would likely introduce helpers as a dependency. The helpers module in turn has no dependencies. So, this shouldn’t be a problem unless it is desired to keep all these low level modules free of any dependencies.

👍 Sounds like a plan! I completely agree that @turf/flatten can be simplified.

@dpmcmlxxvi Feel free to send a PR to the @turf/meta module with your proposed solution, looking forward to it!

I still plan on updating @turf/flatten with new flattenEach. Just need to find some free cycles to get back to it soon.
