This is the minimal C-side dependency for a bug fix in lua-scripts, darktable-org/lua-scripts#677, which fixes wrong colors in the
ai_raw_denoise.luaexample script.The script needs per-channel WB normalization to feed the bayer rawdenoise model the daylight-WB'd input it was trained on. The current Lua tensor API has no per-channel arithmetic and no element-wise multiply, so there's no viable Lua-only workaround – per-element
get/setis ~60M Lua calls per image and unusable.
