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
What about:

```python
def _create(func, error_message, *args):
    try:
        func(*args)
    except:
        # do stuff
```
