Chime support enhancements
# Feature Request

### Description
Hi @dgreif , thanks for your continued support of this API and thank you for your consideration of these two minor requests below.

I've recently had a few request to support wifi status with chimes in ring-mqtt but currently this isn't available via the API.  I'd like to see a "getHealth" function for chimes similar to the one for cameras.

Also, as a super minor enhancement, adding support for chime_v2 and chime_pro_v2 for more correct model numbers might be nice as well.

### Describe the solution you'd like
I think you should be able to just copy the getHealth() function from cameras as the behavior is basically identical.

### Describe alternatives you've considered
I actually implemented my own function to get the health status via a call to restClient directly and it works great, but a getHealth() function would be nice for consistency between cameras and chimes I think.  This is the code I'm currently using:

```
const chimeHealth = await this.device.restClient.request({
    url: clientApi(`chimes/${this.device.id}/health`),
    responseType: 'json'
})
```

I've also manually addressed the model name in my code as well, it's a really minor issue of course.
