i tried on my machine, without avx512 (intel gen 13) here's my /proc/cpuinfo

Describe the bug
We use Camaro on Azure Kubernetes cluster.
Some new Azure VM have no "avx512" support flag on the CPU.
The Camaro library seems to not support this kind of CPU and failed.
CPU signature = Camaro KO

Minimal Script To Reproduce
Try to use Camaro on Azure VM which has no avx512 cpu flags.
