Search for empty fields #611

Is your feature request related to a problem? Please describe. I'd like to be able to search for the assets of a catalog where a given column is empty (isnull())

Describe the solution you'd like cat.search(my_col=None) to return lines where cat.df[my_col].is_null().

Describe alternatives you've considered Fillna the df and search for the filling value.

Additional context I can submit a PR.
