[CB-2905] Exif geolocation meta data tag writing

UIImagePickerController does not return geo data, CDVCamera is now a CLLocationManagerDelegate
when image is taken, CDVCamera begins gps update, waits for success/fail
if success, writes geo data to dicitonary which is passed to tag writing
if fail, meta data written as normal
