Google map Reverse Geocoding

These are the optional parameters: result_type and location_type - can we add them ?

@Nyholm or @willdurand I'd also like this kind of functionality and I'm ready to send a PR for it.

Just some things to ask you upfront:

1. result_type and location_type can be set through the constructor

public function __construct(HttpAdapterInterface $adapter, $locale = null, $region = null, $useSsl = false, $apiKey = null, $result_type = null, $location_type = null)

(as last parameters for backwards compatibility)

1. result_type and location_type can be set through setters
2. Extend buildQuery method
3. Create new Exception class InvalidRequestException and throw it on status = INVALID_REQUEST responses

Please add your thoughts and comments & tell me if you approve this approach.
I'd appreciate a quick answer, so I can get started fast.

Cheers,
Chris
