/**
* Solution based on thomaswue solution, commit:
* commit d0a28599c2
* Author: Thomas Wuerthinger
* Date: Sun Jan 21 20:13:48 2024 +0100
*
* The goal here was to try to improve the runtime of his 10k
* solution of: 00:04.516
*
* With Thomas latest changes, his time is probably much better
* already, and maybe even 1st place for the 10k too.
* See: https://github.com/gunnarmorling/1brc/pull/606
*
* But as I was already coding something, I'll submit just to
* see if it will be faster than his *previous* 10k time of
* 00:04.516
*
* Changes:
* It's a similar idea of my previous solution, that if you split
* the chunks evenly, some threads might finish much faster and
* stay idle, so:
* 1) Create more chunks than threads, so the ones that finish first
* can do something;
* 2) Decrease chunk sizes as we get closer to the end of the file.
