[Feature] Possible to retain a device that left the network?
### Problem description

Sometimes someone (kids) would accidentally reset a device and it would leave the zigbee network. Adding it back is easy but the accessories in HomeKit get reset and have to be customized and added to automations/scenes again.

### Suggested solution

Would it be possible to provide a list of devices in the plugin config to retain even if they leave the network?

Would be even better if they can marked as unavailable when they leave.
