Okay, let's do this.

|---|---|
| 13.191s | dotnet run -c Debug --project OneBee -- ../data/data_100m.txt |
| 11.170s | dotnet run -c Release --project OneBee -- ../data/data_100m.txt |
| 11.564s | dotnet publish -c Release OneBee && OneBee/bin/Release/net8.0/win-x64/publish/OneBee.exe ..data/data_100m.txt |
| 104.404s | cargo run -- ../data/data_100m.txt |
| 9.614s | cargo run -r -- ../data/data_100m.txt |
All I can say is wow. The difference between debug and release Rust is massive. Rust is outperforming C# at its best, but just barely.
Treat the temperatures as 16 bit signed integers and parse them by hand. Switch from rolling average to accumulating the total temperature in a 64 bit integer and averaging at the end.
Going forward, I'm only going to look at Release builds. Also skipping AoT because it didn't make a difference.

| 7.327s | dotnet run -c Release --project OneBee -- ../data/data_100m.txt |

.NET has overtaken Rust. Neat.
Copy paste some code to avoid some of the string conversions. Still allocating a string for each lookup - not great

Remove my hacky fix and do a more legitimate fix. Not sure if it improved perf or if that's just margin of error.
