Crashing with IPv6 connections

[dkulp]

I'm working on supporting some of the wled API on a more "full featured" device. One part of that is that the device supports IPv6. When WLED-native detects this service, there are a few issues:

1. The IPv6 address is too long to display in the list of devices. The list cannot be made wide enough to display it.

2. When clicking on the device, wled-native crashes

I actually think the best fix would be to limit the connection to ipv4. This allows

Note: the _wled._tcp service is only registered with mdns on ipv4 and a " avahi-browse -a | grep wled" from a linux box confirms that. Ideally, wled-native would check the registration and force ipv4 appropriately.
