PlacePicker still uses legacy api

[ThomasShih]

I think google needs to update this component library

Environment details

1. Specify the API at the beginning of the title (for example, "Places: ...")
   -- Places
2. OS type and version
   -- Mac OS,
3. Library version and other environment information
   -- 0.6.14

Steps to reproduce

Use PlacePicker

main.js:176 You’re calling a legacy API, which is not enabled for your project. To get newer features and more functionality, switch to the Places API (New) or Routes API. Learn more: https://developers.google.com/maps/legacy#LegacyApiNotActivatedMapError
