[BUG] Cannot add TV accessory due to setup code already being used by another plugin
**Describe the bug**
I cannot add the Harmony TV accessory to Homekit, as the same setup code is being used by another TV service created by a different homebridge plugin - specifically, the [homebridge-webos-tv](https://github.com/merdok/homebridge-webos-tv) plugin. These are both currently setup as child bridges:

> [1/1/2024, 9:43:52 PM] Please add [harmony-hub-TV 0E00] manually in Home app. Setup Code: 031-45-154
> [1/1/2024, 9:43:51 PM] Please add [LG CX 77 B71B] manually in Home app. Setup Code: 031-45-154

**To Reproduce**
Setup a TV accessory with a different plugin with the same setup code. 

**Expected behavior**
A unique HK setup code, or a way to regenerate a different code.

**Config**

**Additional context**
I'm not sure if there any rules around the setup codes being generated - are codes supposed to be UUIDs, or are they more deterministic in that the placement of numbers in the code indicate something to HomeKit?
