"Auto" IP address detection does not work when localtuya is installed

[make-all]

Describe the bug
When IP address is set to "Auto", tinytuya uses device discovery in the background to find the IP address. If localtuya is installed, it already has the ports required for Tuya discovery open, so trying to open them fails.

To Reproduce

1. install localtuya
2. add a new Tuya Local device with IP address set to "Auto"

Expected behavior
Users expect things to just work, even though there is a technical explanation for this.

Additional context

The below exception is now caught in main, but the core problem remains (just is more gracefully handled now).

Do not use localtuya and tuya_local together, both will use discovery every few seconds and some devices do not handle multiple communication in quick succession very well.

For 3.3 devices, both discoveries may cause "Unable to find device on network (specify IP address)", "Access denied", "Address in use". "Access denied" was only fixed after resetting every Tuya device I own to fix this problem.

I don't own any 3.4 device but 3.5 devices run without problems.

Edit: This could also be reproduced by using localtuya and tinytuya in debug mode, as well as using localtuya and pinging the device.

[make-all]

Added wontfix label, as this is a technical limitation that can only be fixed by architectural change in Home Assistant to allow integrations to share a common broadcast port.

For me it was because I have B818 router and tp-link mesh network. Tp-link needed to put away from wifi mode
