Group autocomplete requests with session token

[ollieh-m]

Given google's pricing changes for autocompletion requests, I believe it's now significantly cheaper to group autocomplete requests with a session token: https://developers.google.com/places/web-service/autocomplete

Is it possible to add a session token to the autocomplete requests made by getAutocompletePredictions in this library?

Many thanks

First off, get on the new beta release, see #198 to get started. Would most likely add your request in an update but this is automatically done for you on android (in the new release) - so this only applies to iOS
