Fix weird malformed license notice in test file

[AdamGS]

Summary

I was trying hawkeye which has some nice features reuse doesn't have, and it found this weird issue.

[a10y]

sorry, but think we need to contact Vortex contributorsuse crate::dtype::Nullability; and ask for their permission before we change the license

⚠️ Unknown Walltime execution environment detected

Using the Walltime instrument on standard Hosted Runners will lead to inconsistent data.

For the most accurate results, we recommend using CodSpeed Macro Runners: bare-metal machines fine-tuned for performance measurement consistency.

⚠️ Different runtime environments detected

Some benchmarks with significant performance changes were compared across different runtime environments,
which may affect the accuracy of the results.
