can you add Color palette support?

[Ranko-Saotome]

I'd like to ask if it's possible to incorporate biome support for nodes that rely on color palettes to texture. For instance, in games such as MineClone2 and mineclonia, the same node is utilized but with varying colors. The maintainer of MineClone2 mentions this is related to a param2 palette.

this is already a thing (i know it under the name "param2 coloring") and is supported by the colormapping package already (which the mapserver uses):

https://github.com/minetest-go/colormapping/blob/a89b82db025cd41b4b74f228a2e96cb619c14392/colormapping.go#L179-L195

I think you are just missing an entry in this file: https://github.com/minetest-go/colormapping/blob/main/colors/extended_palette.txt

You can also just post the names of the nodes and point me to the palette-png here if you want 👍

(fyi: i'm planning to implement some kind of autoconfiguration which also would include palette and such things into a future release but i'm nowhere with that yet)

All the nodes with palettes in Mineclone2: (mcl_core:vine uses a cropped palette because it's colorwallmounted)
