package(autocomplete): Add function to obtain predictions in geocode methods

[tbor00]

Is your feature request related to a problem? Please describe.
Getting predictions out of the hook could be a great advantage if we did not use react, we could add it and use it without the need for our project to have react.

Describe the solution you'd like
Add method to obtain predictions like as:

const getPredictions = () => {
  const autocomplete = new libPlaces.AutocompleteService()
  autocomplete.getPlacePredictions({})
}
