Add support for Saturn 4 Ultra

[vvuk]

S4U uses protocol version 3.0.0 and has more extensive features from what I can see (file listing! access to the camera feed!) but work will be needed.

The protocol seems to have changed. It's now a websockets based thing, using the same structure as before. The broadcast reply includes the IP address, and the host can make a HTTP request to port 3030 to upgrade to a websocket connection. After that, command requests/replies proceed much like they did with MQTT (including leftover "topics"; maybe there's still a MQTT way to do this, but this is much simpler). Here's a stream of ChituManager talking to my S4 Ultra, including enabling the video:

UDP broadcast reply:

Port 3030 is the http port; used for a websocket upgrade, as well as to fetch data from the printer
