iOS and Android differences

It might be worthwhile to document the different fields of Message which are for iOS, Android, or both.

Hi @bontibon
If you need docs, here is description https://firebase.google.com/docs/cloud-messaging/http-server-ref#notification-payload-support

Later, I am gonna update GoDoc, or, if you want, you can do it :)

@bontibon You can try gorush which support APNS for sending the notification to the iOS device.

It looks like fcm.Message does not even support the platform specific fields looking at https://firebase.google.com/docs/cloud-messaging/concept-options#setting-the-priority-of-a-message these fields should be sent as

{
  "message":{
    "topic":"subscriber-updates",
    "notification":{
      "body" : "This week's edition is now available.",
      "title" : "NewsMagazine.com",
    },
    "data" : {
      "volume" : "3.21.15",
      "contents" : "http://www.news-magazine.com/world-week/21659772"
    },
    "android":{
      "priority":"normal"
    },
    "apns":{
      "headers":{
        "apns-priority":"5"
      }
    },
    "webpush": {
      "headers": {
        "Urgency": "high"
      }
    }
  }
}

But fcm.Message lacks the fields for "android", "apns", and "webpush" or does this project strictly use the legacy API documented here https://firebase.google.com/docs/cloud-messaging/http-server-ref

@vendion this lib supports only legacy fcm API, no new (v1) API.
