Process chunks in parallel

Refactor how the image layer partitioning is done
It got pretty ugly after the last commit.

This will be much easier to parallelize, but that's not included in this commit yet.

Heikki Linnakangas	2e7e5f4f3a	Refactor how the image layer partitioning is done It got pretty ugly after the last commit. Refactor it so that we first collect all the key ranges that need to be written out into a list of tasks, then partition the tasks into image layers, and then write them out. This will be much easier to parallelize, but that's not included in this commit yet.	2024-09-13 05:41:35 +03:00
