Updated keys!!

Hey @ewels , looks like it needs more than just 2 *keys* :sweat_smile: Now I really believe thats all it needed.
General comment, could this also be written as follows?

```python
runs.append({
  'name' :        card.name,
  'path' :        os.path.join(pm.archive_folders,run['name']),
  'flowcell_id' : card.name.split("_")[-1][1:],
  'date' :        card.name.split("_")[0],
  'position' :    card.name.split("_")[-1][0]
})
```

Personally I find this easier to read, but it makes no difference to the execution really. @remiolsen @guillermo-carrasco @pekrau - is there a PEP answer to this?
