Show HN: WinZST > 7-Zip fork with first-class compressed tar support on Windows

WinZST is a 7-Zip fork that extracts compressed tar archives directly to their final directory instead of materializing an intermediate `.tar`.

In one 11.8 GiB `.tar.gz` test containing mostly video, WinZST took 51.87s from archive → `foo/`; 7-Zip took 103.53s across `.tar.gz` → `.tar` → `foo/`.

It's great that you found a way to simplify the extraction algorithm.

Can you share the PC specs you used to run the test for both the WinZST and 7-Zip experiment?

Besides speed, we should check the compression ratio also when comparing compression software.
