Add more extruder temperature options

[koenpunt]

When printing high temperature filaments, we need the extruder at temperatures higher than 240ºC.

Would simply adding them like this be sufficient? Or could this cause problems with printers that do not support the higher temperature ranges? I assume the temperature is also limited by klipper/moonraker and probably also the firmware of the machine.

Update: simply adding them worked, but resulted in suboptimal UI. By splitting over 2 lines, and resizing the rows, it now looks decent;

Adding an additional item that allows entering a value might be better? Not sure if I can figure out how to develop that tho..

After some more tinkering I managed to make it look like this;

Nice 👌
Does lvgl set the button size based on the text size?
I think fixed size buttons will look better.

Your other commits don't show up here...
Curious to know what you did to get it to build? I have some changes for the small Nebula pad screens.

I'm using Ubuntu 24.04.

I only used cross compile on a droplet on digital ocean, since I work on Mac myself.
Following the development guide worked for me.

@henrivdr also see this issue, which refers to a commit that only enables static linking when doing cross compilation. With that commit I'm able to build and run on Ubuntu 24.04 ARM

This one #110 , right?
