Nice Speedups

Hi @mattkretz ,

You asked about feedback and besides the issues I opened here, we also got nice performance numbers now.

vir-simd helps to give us phenomenal speeupds for our compute-bound kernels in ImpactX, up to order-of-magnitude improvements (w/ SP):

So if GSI is looking for a new particle beam dynamics code for FAIR and related accelerators, send your colleagues over to us please :)

Thanks for your library!! 🚀 ✨

Can't wait to use this directly out of C++26/29 in the future 🎉

Cheers from Berkeley,
Axel
