[BUG] Testing 224 - Debug info on growth-scale reports incorrect data or significance unclear

note that any ranges of block lights will be changing, so no point doing extensive testing…

IMPORTANT: The light sources will also be rebalanced to bring a more consistent lighting model to voxel light sources.

also looking to hopefully (assuming no massive backlash… ) make the light sources scale properly with their colour as well. Aka black gleam is basicly 0 light source, but white gleam is a very bright white source. Currently that is just… “weird”, with black gleam being just as bright (and white) in lighting as the white gleam is on its surroundings… which is just bloody weird.
