Add Floodlight Pro to device list
# Bug Report

### Describe the Bug
Not really a bug per-se, at least I don't think so, but I'm starting to get some queries about Floodlight Pro, which currently isn't in the device list ("kind": "floodlight_pro").  Admittedly it seems to mostly just work anyway, although a user reported that they don't get light/siren switches, which I don't understand as the device discovery data looks completely normal to me.  I'd think the only side effect of not being in the list would be the model showing as "Unknown Camera".  Am I wrong about that?

### To Reproduce
Have a Floodlight Pro, see it's not supported!  :)

### Expected behavior
Device should report correct model (Floodlight Pro)

### Screenshots/Logs
Take a look at device discovery data from a Floodlight Plus vs Floodlight Pro in this ticket:

I don't see anything that should keep it from not working, only the "Unknown Model" issue, which is super minor, but I figured I'd provide the information needed to add it anyway as I'm sure your users will end up with this camera soon enough as well as I already have two reporting the issue and another with the camera on the way.

Thanks!
