Default AVX-512 support in latest CADO

The latest revision to CADO includes improvements to the lattice reduction routine, including the addition of AVX-512 code for what I believe is the first time. There is a speedup of a few percent in sieving even on non-AVX-512 systems, so it should be worthwhile for everyone to upgrade - though of course it's possible there are bugs in the new code that are yet to be discovered.

I don't have access to an AVX-512 system myself, but I'd be interested to see how big the improvement is for those who do.
