Cannot set badge without also including a message_body

[Atheros1]

But I don't want to include a message body, I just want to set the badge count. Use cases for this abound. Currently I've had to fork PyFCM and do like this:

from PyFCM.pyfcm import BaseAPI
import json
import config

base_service = BaseAPI(api_key=config.FCM_APIKey)

pushToken = "big-long-private-push-token-asdofiauusifaosdfuadfnua9sd8fnu9asd8f"
fcm_payload = dict()
fcm_payload['priority'] = 'high'
fcm_payload['notification'] = {}
fcm_payload['notification']['badge'] = 5
fcm_payload['to'] = pushToken
payload = (json.dumps(fcm_payload, separators=(',', ':'), sort_keys=True)
.encode('utf8'))

print base_service.send_request([payload])

Can you kindly make a fix and submit a PR? It will be much appreciated
