Add support for fans

[smockle]

Fan control switches, such as the GE 14287, can be added to the Ring Alarm Base Station via “Devices > Set Up a Device > Security Devices > Works With Ring”.

Once the device is added, the Ring app prompts you to select a category (options are “Fans”, “Lights” and “Outlets”) (screenshot below):

Homebridge supports a Fan Service. This PR enables the homebridge-ring plugin to identify fan control devices as Fans to HomeKit.

Without this PR, the plugin identifies these devices as dimmable lights. This is because Ring reuses the switch.multilevel deviceType for both fans and (multi-level) switches. This PR differentiates the two device types by using the value of categoryId. Fans and multi-level switches have categoryId 17 and 2, respectively. This can be seen by modifying examples/example.ts line 47 to log the entire device object with JSON.stringify(device).

I published [email protected] for testing. Additional screenshots below:

@smockle thank you for the PR! Everything looks great, I'll just need to do some additional steps to ensure compatibility if there was already a Lightbulb service created. The really ironic part is that I have that exact GE switch which I am using for a fan and didn't realize that Ring had the categories you could choose from 🤦‍♂. Really appreciate the help!

@smockle released in v5.4.0. Let me know how it works for you after the upgrade. It should automatically remove the light and add a fan

@dgreif Thanks for the update! I upgraded to 5.4.0 last night, and it’s working well here.
