David MannandClaude Opus 5.5 39aa849b47 Raw: open monochrome LinearRaw DNGs (1 sample per pixel) (#3497) (#3503)
A one-sample LinearRaw DNG (VueScan film scans, Leica Monochrom) was
rejected as "LinearRaw data with 1 samples per pixel". The DNG decoder
now accepts it and develop renders it as neutral grey: the one sample
fills all three channels, white balance, colour matrices and camera
looks do not apply, and the output is R = G = B in 16-bit ProPhoto.
io skips the preview colour fit for such files.
