BUG: Jobflow not compatible with maggma 0.38.0+

[Andrew-S-Rosen]

Just reporting what I shared via Slack. Jobflow works fine with maggma==0.36.0, but not via the new maggma version in #61.

import jobflow # in a clean Python 3.8 conda env (Windows) after pip install jobflow

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

    default_factory=lambda: JobStore(MemoryStore()),
TypeError: Can't instantiate abstract class JobStore with abstract methods _collection

Edit: Actually, even with maggma==0.36.0, things aren't working when I try to access the store (looks like a maggma issue). The traceback below is in a clean Python 3.8 environment (Linux) after doing pip install jobflow but setting maggma==0.36.0 and running run_locally().

TypeError: 'Collection' object is not callable. If you meant to call the 'authenticate' method on a 'Database' object it is failing because no such method exists.

@utf, do you know of a current workaround for the above? Unfortunately, I haven't been able to store results from any Jobflow jobs and am struggling to find the combination of packages that gets it working again, even if temporarily...

I just pushed a fixed to the main branch. If all tests pass I'll update the dependencies and release a new version. I think maggma changed the abstract Store interface.

Fixed in v0.1.6
