Add Geocoding API to setup instructions

[shaun-adam]

Thanks for this great component!

Took me a few minutes to figure out why I couldn't get it to authorize my requests. I eentually figured out that I need to enable the Geocoding API where as the readme only mentions Maps and Places

Perhaps adding that would help other new users?

I was just about to raise an issue because my config was not working when I saw your comment @shaun-adam . Many thanks, my config is now working. Yes, better instructions on the Google API side would smooth the way for the use of an otherwise excellent component!

I created PR #31 for this.

and how do I make that? created a api_key from the https://console.cloud.google.com/google/maps-apis/credentials but still get the Platform error sensor.google_geocode - Integration 'google_geocode' not found.

have this in configuration.yaml under sensor

• platform: google_geocode origin: device_tracker.xxxx options: city api_key: xxxx
