"darktable/tools/noise/gen-profile" not recognising Canon CRW raw files
I have had no success in profiling my Canon EOS-300D which produces .CRW raw file. The gen-profile program simply does not recognise them. This is still apparent on git master.
I have attached one shot per ISO value. I have tried converting to .DNG files using Adobe DNG converter 220.127.116.114 following Roman's suggestion to disable compression and these are recognised but the quality is doubtful.
Another problem is that the gen-profile program incorrectly names the camera in the generated profile so I had to rename it manually so that darktable could recognise it. This may or may not be a consequence of using DNG files though I don't know.
Fix #11607: Make gen-profile work with EOS 300D
The samples only had the ISO in Exif.CanonSi.ISOSpeed so we should look
at that field, too.
