Try to work around build errors with an updated seqwish.

@AndreaGuarracino I was trying to get around -mcx16 because it prevents ARM builds.

I think this post explains what is happening. Indeed, this commit was necessary to be able to build seqwish without the -march=native option. Moreover, also on my laptop, with Ubuntu 22.04 and Intel CPU, I am not able to build the current seqwish's master with the -DCMAKE_BUILD_TYPE=Generic option.

Now, by using this seqwish's commit that forces the -march=haswell option when we build with -DCMAKE_BUILD_TYPE=Generic or -DCMAKE_BUILD_TYPE=Debug (not -DCMAKE_BUILD_TYPE=Release, so without -march=native), we are able to fully build PGGB's Dockerfile with the latest seqwish, but I am not sure if this destroys stuff on ARM systems. I see that with aarch64 ASAN doesn't like the result.

Building seqwish with -DCMAKE_BUILD_TYPE=Release is the only current way to get it on aarch64 (ekg/seqwish@6bc8c87), so the doubts remain.
