Add and test support for new Dyson devices (Device owners' help is appreciated!)

[dotvezz]

Yesterday, Dyson announced the following products:

• ~~Purifier Big+Quiet~~
  • Support added in v1.1.0
• ~~Purifier Big+Quiet Formaldehyde~~
  • Support added in v1.1.0
• 360 Vis Nav

Based on previous product releases and MQTT/Wifi messaging patterns, adding support for these devices should be trivial. However, testing the new devices with this integration will require the assistance of device owners.

If any owners of the new devices would be willing to share messages/logs that would be awesome.
