While generating maps with minetestmapper I encountered a problem: the colors.txt file is not always provided by the game (VoxeLibre does,
Asuna does not) and when it does there is a long list of unknown blocks
and I suppose the file has not been kept up-to-date for quite some time. Moreover mods may add blocks of their own.
To fix this upstream explains in their README.rst we need use the `util/generate_colorstxt.py` script to generate this file. Unfortunately
it is not currently installed by the package because the cmake rules
does not take care of it.
It only requires python3-pil. I have tested it on a server on bookworm
with two maps and it appears to be working.
Would you consider adding it in the package please?
