2020-05-03qcam: dng_writer: Generate thumbnail in RGB formatLaurent Pinchart
While the DNG specification supports greyscale ("BlackIsZero") for thumbnails, RawTherapee seems to have trouble reading them. Generate thumbnails in RGB instead (but still with greyscale content, to avoid having to interpolate colour components).

2020-05-03qcam: dng_writer: Populate DNG tags from metadataLaurent Pinchart
Populate the DNG black level, ISO speed rating and exposure time from metadata. The ISO speed rating and exposure time are standardized as EXIF tags, not TIFF tags, and require a separate EXIF IFD.

2020-05-03qcam: dng_writer: Output thumbnailLaurent Pinchart
Generate a greyscale, 1/16 resolution thumbnail and add it to the DNG file. This requires shuffling the RAW image generation as the thumbnail has to be stored in the main IFD as per the DNG and TIFF/EP specifications.

2020-05-02qcam: Add DNGWriterNiklas Söderlund
Add an initial DNG file writer. The writer can only deal with a small set of pixel formats. The generated file is consumable by standard tools. The writer needs to be extended to write more metadata to the generated file.
