The Z5II has no colour matrices and its NEFs carry no preset table, so its Temp slider
showed the relative -100..+100 scale. A small per-model table (crates/raw/src/kelvin_builtin.rs)
gives five (Kelvin, multipliers) points that feed the existing KelvinPresets curve: the NEF
decoder attaches them to ColorData::kelvin_presets and kelvin_presets::covers accepts the model.
Points: as-shot WB_RBLevels of the body's own shots at Incandescent, Direct sunlight, Kelvin
5500 K, Cloudy and Shade, placed at the temperature the camera itself writes for each preset
(maker note ColorTemperatureAuto: 3000, 5210, 5500, 5990, 8000 K). Fluorescent and flash are
left out. Natural Auto (camera: 5030 K) reads back at 5036 K.
