fix biothings_client import error

[dakesan]

While following the tutorial and attempting to import celloracle, I encountered an import error caused by the latest version of biothings_client, which is a dependency of genomepy. Below is the error traceback:

ImportError: cannot import name 'alwayslist' from 'biothings_client' (/home/ubuntu/mambaforge/envs/test_celloracle/lib/python3.10/site-packages/biothings_client/__init__.py)

To resolve this issue, I specified a version of biothings_client that includes the alwayslist function. This resolved the import error successfully.
