Attached is the presets.txt output from the gen-profile script for the
Sony RX100 Mark 2. I hacked them myself into src/common/noiseprofiles.h
and Darktable seems to behave correctly - it detects or interpolates the
correct profile and the results look good to my eye. I included all ISO
settings that are manually selectable, but the RX100M2 autoselects
intermediate ISOs when set to auto. Let me know if you need the PDFs or
some sample images.
