DDP with mdns names - feature request

[DarthWeber]

Is your feature request related to a problem? Please describe.
Sometimes i need to change the IP of my WLED Controller. Since i am using DDP i need to change the according ip in the DDP settings

Describe the solution you'd like
A test field which could be filled with the IP or the mDNS names like wled-1234.local

Describe alternatives you've considered
fixed IP - but in rare cases like changes of the router fixed IPs are lost.

Thank you for your ideas for making WLED better!

This may be related to #4671 as I do not see a mDNS client stack, and that issue also needs it.

Seems to work (with a caveat).

Was there a PR or just commit straight to main @blazoncek ?

Can we update with reference then close if completed?

[blazoncek]

My fork only, for now, as there are some issues to be resolved and thoroughly tested.

Can we update with reference then close if completed?

Once PR is made and merged.
