Should resolve #90

• update dill & multiprocess dependencies
• enable multiprocessing on Windows

TODO:

• look into consequences of upgrading dill dependencies

---

I got it to work on Windows - the following observations:

• dill.settings["recurse"] = True is not necessary
• we cannot pickle (dill) generators pickle iterators and generators uqfoundation/dill#10
  => code needs some updates (currently done quite hacky)
• multiprocessing on Windows often works slower than non-multiprocessing. Largest improvement that I noticed was like 5%...

As for now I will just close this PR and keep the implementation as it was
