Feature: Firmware Update Support

[cmgrayb]

Is your feature request related to a problem? Please describe.
Currently, the Dyson integration detects when firmware is available, however when trying to update the firmware, nothing is updated and the update gets stuck in an updating state within Home Assistant

Describe the solution you'd like
When clicking update in Home Assistant, the API command to update the device should be sent and the device updated.

Describe alternatives you've considered
Firmware update availability is working, so the user can currently update within the app, but there is an update button which is causing confusion and should work if possible per Home Assistant Core requirements

Help wanted:

This enhancement is currently pending the next firmware update for a physical device where we can capture the MQTT messages indicating progress. If someone happens to have a device that they can monitor the MQTT messages on and a pending firmware update, we need the message logs from the /status/software topic, in particular what the key name of the messages is. For more information, please see the progress documentation
