Exposing Unifi Chimes for volume control
I recently purchased a Unifi UP-Chime, and like to have some automation attached to it via Homebridge. In the evening I want the volume to be turned completely down, and the morning (from a set time, to have it on again).

I am a software-engineer, and have already made a mock using CURL HTTP command with JSON payload to set the Chime volume directly (this works perfectly), examples below.

Let me know what you think of this feature, It would help me out a lot.

**Ideal solution/ goal**

The ideal goal would be a switch (or brightness control) that can set the Chime volume.

**Background**

After studying the API, using this repository as a guide, I managed to list all chimes, and update properties accordingly via raw CURL HTTPS requests. As this homebridge-plugin offers a great implementation already, I was wondering if it is possible to have it extend with chimes.

**API mock**

List all chimes
```bash
$ curl -k -X GET https://nvr-host/proxy/protect/api/chimes --cookie "*****" -H "X-CSRF-Token: ****"
```

Set Volume to n-percentage
```bash
$ curl -k -X PATCH https://nvr-host/proxy/protect/api/chimes/<chime.id> -H 'Content-Type: application/json' -d '{"volume": n}' -v --cookie "*****" -H "X-CSRF-Token: ****"
```
