Plugin has stopped working in entirety (no alarm control, no camera access)
# Bug Report

### Describe the Bug
Ring plugin is no longer functioning, and appears to be erroring out on the following line during init:
"Ring floodlight_v2 {uuid} is offline or on cellular backup.  Waiting for status to change"

It's not clear if floodlight_v2 is a misnomer. While I do have one v2 floodlight, and two v1s, all of them have been online and powered for weeks, if not longer (they are hardwired). I do have a stickup cam whose battery died a few days ago, around the same time this started happening, however I have recharged and it is online in the native Ring app (along with the other cameras, and all of the Ring devices).

After confirming everything is online and connected in the Ring native app, I have tried rebooting Homebridge multiple times to no avail. I have also tried using a freshly generated refreshToken to no avail. Turning on debug logging does not print anything further.

### To Reproduce
Steps to reproduce the behavior:
 - Start Homebridge
 - Attempt to view Ring cameras or control alarm
 - No error or logs show up at all - the line mentioned above is the last thing that ever gets logged, which is during init of Homebridge

### Expected behavior
Should behave as normal

### Screenshots/Logs
Log line provided above, that is the only error message, and the last log from the plugin

### Additional context

### Homebridge Ring Config
Post homebridge-ring platform config  _without sensitive information_
```
{
"refreshToken": "xxx",
"debug": true,
"platform": "Ring"
}
```

### Environment

 - Node.js: v12.18.3
