AttributeError: module 'zarr' has no attribute 'MemoryStore'`

[fluviotect]

Hello,

First off, Fastscape looks like a cool and very promising tool. Cheers for your effort and sharing.

I get the following error when running the basic model in the tutorial notebook (01_run_basic_model.ipynb).

I get the same error when I run:

• locally (git clone of fastscape-demo repo)
• on web (Binder)

Cheers

I got the same error and opening a Issue in the main fastscape repository. I solved the error installing the package locally with python 3.10.0
