TODO

[insolor]

• Add docs in the code
• Releases workflow (add new tag, add release page with a changelog...)
• Implement Counter.mostCommon using heap sort
  • Use heap sort implementation from the standard library: https://ziglang.org/documentation/master/std/#std.sort.heap

Delayed/rejected:

• Split Counter into Counter (based on AutoHashMap) and StringCounter (based on StringHashMap) - tried, didn't work out
