For the delivery I just noticed that I still need to do #50 done

[falko-strenzke]

use all the AVX2 branches and KMAC branch

• [ ] JRH macht einen kombinierten branch aus den AVX2

[falko-strenzke]

The branch all-pqc already has kyber-avx2 and kmac branches merged.

[TJ-91]

all algorithms are merged now (merged dilithium_avx2 and sphincsplus_avx2).
