Lightroom-converted DNGs carry their camera profile's ProfileHueSatMapData1/2 and ProfileLookTableData (and sometimes ProfileToneCurve). We used only the colour matrices, so such DNGs rendered flat and muted. - raw: new `profile` module reads the tags (DNG spec ch. 6: value-major, hue-middle, saturation-minor tables, wrap-around hue, tri-linear lookups, sRGB value encoding) from the raw IFD or IFD 0; malformed tags are ignored. - engine: the raw loader applies the hue/sat map (interpolated by the same illuminant weight as the matrices) before BaselineExposure and the look table after it, in linear ProPhoto; a ProfileToneCurve becomes the source's camera tone. Without one the standard base tone is kept. - dngwrite keeps the look with the data (conversions, smart previews, merges). - Render cache version 7.
