Announcing the latest release of lo with lots of good gifts! 🎁

🌊 First, a big thanks to @​d-enk for making lots of performance improvements in the recent weeks.

🧪 Second, this release introduces a new simd experimental package. If you run on an amd64 architecture and a recent CPU, you can perform very fast operations thanks to SIMD CPU instructions.
-> Documentation: https://lo.samber.dev/docs/experimental/simd

💥 Third, this version adds *Err variants of many lo helpers (like MapErr, FlatMapErr, ReduceErr, etc.) whose callbacks can return an error and short-circuit execution when one occurs.

[!NOTE]
The simd sub-package is considered not stable. We might break the initial API based on developers' feedback in the coming months.
