cartoframes quickstart example in jupyter-notebook breaks on geocoding

[tdimeola]

Just going through the cartoframes quickstart with the Starbucks example and code breaks on:

`from cartoframes.data.services import Geocoding

stores_gdf, _ = Geocoding().geocode(stores_df, street='address')
stores_gdf.head()`

I've attached a screenshot. Looked for this issue elsewhere but couldn't find anything. Thanks.
