Use the new zigbee2mqtt api

[matbech]

Use the new zigbee2mqtt api to request a network map as documented here: https://www.zigbee2mqtt.io/information/mqtt_topics_and_message_structure.html With this change it is possible to use this integration when zigbee2mqtt is configured with:

advanced:
  legacy_api: false

FWIW: I've just tested this commit and it works like a charm for me.

Unfortunately not working for me. The map is just stuck on No update received yet. Re-checking with an ever increasing number...
