Unable to explore a pandas DataFrame

[lodagro]

Describe the bug

A ValueError is raised when exploring a pandas DataFrame, which is related to objexplore.utils.is_selectable.

In [1]: import objexplore                                                      
In [2]: import pandas as pd                                                    
In [3]: df = pd.DataFrame()                                                    
In [4]: objexplore.utils.is_selectable(df)

Thanks for the report, fix is in v1.4.4 - upgrade with pip install objexplore --upgrade and see if the bug persists.

Thank you!
