WLED 512 channels per universe support

[Ferqli]

Hello,

according to #968 and #998

or simalar solution according to #2325 or #1663

I would like to request an option in WLED to use a 512-channel universe instead of 510, or any other suitable solution.

I am using MadMapper to map every LED, and I am currently forced to add a fixture every 170 LEDs. I have an installation with 4900 LEDs distributed across 8 ESP32-ETH01 devices, so you can imagine the number of fixtures I need to create.

To provide a concrete example:
My BlueBox ETH corresponds to one ESP32 with 3 outputs.
On each output, I have one 5m LED strip (300 LEDs), which I organize into 3 prisms that I have created.
In MadMapper, the setup looks something like this (see attached pictures). It's not just about the fixtures I’ve already created, but also about positioning these fixtures in the space to ensure the input content matches the real-world layout.

One day I found this topic witch came with a nice solution using ArNetominator and correct the Artnet communication signal but it's only for windows. The equivalent is midimonster for mac, but I'm still stuck with an other issues

I love WLED and plan to continue using it for a long time, but this feature would make it so much easier for people like me who create light installations with WLED and use professional software like MadMapper, Resolume, etc.

Thank you for considering this idea to improve WLED!
