Deal with images in a linear color space as input. Add a mode for only adjusting the image luminance. Compute an orientation info for every detected color checker. Option to select the best oriented color checker or combine them if several are detected.
… and full correction.
…ly for images with a name matching a filter. [hdr merging] Forward the suffix "_macbeth" to the hdr image name if at least one of the merged images has a name suffixed with that.

In some cases, the colors written in the JSON file of the detected checkers
can be set as "-nan". When that occurs, the value is not considered as a
"double", which raises a fatal issue ("cannot converted type to double").
Here, if the requested color value cannot be retrieved, or if it is not
a double, it will be set to 0 instead of stopping the program.
To prevent segmentation faults when attempting to access out of range pixels, we check that the location of the pixel is within the image.
