Use StructVector container in Schelling and Flocking benchmarks

It should provide an improvement in performance, but we need to wait until the new feature is released

@Tortar is this new feature out? ANy chance we can merge this?

[ameligrana]

The feature is still not out actually so it won't work

[Datseris]

do you remember perhaps what is keeping this feature from being out because I thought that your PRs were merged and working fine?

[ameligrana]

nothing in particular I think, I suggested to release this in the past, but we ended up waiting for GSOC work to be finished at the time before releasing and so this is still not out

[Datseris]

Ah, I see. Classic mistake :D I'll be spending time trying to get everything in, and tag a new release, it may take a while given how many new stuff are there. After the release I'll also post a message searching for a maintainer. It is clearly needed!
