Hmm apparently the memory benchmark was faulty, measuring (shared) memory in this settings is pretty hard 🙄 |

(Migrated from #58 to a local branch.)
Parallelizing with mirai + mori allows sharing R objects in memory, meaning less overhead as data doesn't have to be copied between workers.
This will need a bit more testing but I think supporting mirai/mori is going to be a big win as the two basically redefined the modern R parallelism stack.
Currently this allows both doParallel and mirai backends and auto-selects the corresponding backend depending on what is set up.
