Validation
To validate that the .aco file generation is working properly I decided on
the following process:

export few default Color Swatches from Adobe Photoshop 2022
extract them to .csv files and make sure data in that files are matching
to what is in the Adobe Photoshop
generate new .aco files from .csv acquired in the previous step
compare original .aco files with ones regenerated from .csv using:

hexdump examples/utf.aco > utf.aco.hex
hexdump utf-new.aco > utf-new.aco.hex
diff utf.aco.hex utf-new.aco.hex -y


import new .aco files into Adobe Photoshop and compare them with original
Swatches

Notes
I'm aware that original .aco files contain some additional bytes at the end
of the files. Those bytes which will not be present in .aco files generated
by the script. These bytes might be related to
Custom color spaces,
which are not supported by this script.
Nevertheless I was able to successfully import generated .aco files back into
the Adobe Photoshop and use them in my work!
