subscribe to locationMode changes
# Feature Request

### Description
Is there a way to subscribe to location mode changes for Ring Alarm? I cannot seem to find one. Sorry if it's documented somewhere.

### Describe the solution you'd like
Similarly to how we can already subscribe to motion and ding events from Ring cameras. I'd like to be able to subscribe to arm, away or home events.

### Describe alternatives you've considered
Some sort of check every 5 seconds. Not the best
