Allow for a Pandas df when using the cli #170
Description
PR #169 includes these lines:
no_pandas_df_dict = {"pandas_df": False}
conf_export = replace(conf_export, **no_pandas_df_dict)
They were added since cli's summary, csv, skymodel and regions methods require sourcelist to be a utility.containers.ExtractionResults object, not a Pandas df. See bullet 8.
Therefore, we'll need to expand those four functions to also handle Pandas DataFrames.
