WIP: New split lib workflow

We need to:
- [ ] check that meta-analysis is still working
- [ ] finish preprocessing (split libs) connect per prep template
- [ ] make preprocessing async
- [ ] be able to connect to other studies raw data
- [ ] fix metadata summary per prep template
- [ ] add EBI submission
Again, I will do that but enforcing a style that is not auto enforced is a
waste of time, just think about the time we have spent discussing vs. a
simple failure in the build.
