- Chunk loading now is done in a more simple manner. Instead of splitting it into regions and having one file handle for all chunks in the same region, now all chunks make their own file handle for the region, the previous overhead was not worth it, since this seemed to increase performance.
- Speed up of ~15%
- Now the `.read_chunks` function does not return anything, instead it sends event to an mpsc channel.
- Dramatically decreased memory footprint.
