dev-python/numcodecs: version bump 0.15.1

I don't know why, but filter-flags -pipe is strictly required on my system and leads to missing symbols otherwise

Requirement of local -x DISABLE_NUMCODECS_{AVX2,SSE2}=1 is a known problem upstream

I really think this should not be in the ebuild, I cannot reproduce your problem and it does not make sense. There is something weird happening on your end, but filtering this flag here is a weird symptomatic solution.

I totally agree that this should not be in the ebuild if it only fixes the build on my system but not others.

Does it work for you without filter-flags -pipe and without -march=native from the LTO settings?

Somehow it now also breaks for me without filtering -pipe, I am confused.
