After running 'make check', this script can be used to see which tests are not passing, showing the test line and a [XP], [XF], or [F] tag, for each backend.
It can be used like this:
```plaintext python3 lightboard.py [-b] <vkd3d_build_path>/tests/hlsl ```

So we can say "All lights green across the board" in a cinematic way.
