Strip away copyrighted ICC profiles, and fix executable bits

Hi,

Please consider stripping away copyrighted ICC profiles, the images provided have been checked identical to their sources. Please also consider fixing the executable bit of some files from this repository.

Additional gain: the files are smaller while the images are identical.

Given there is absolutely no code change nor any creativity in this proposal, they are not submitted to any copyright, but I’m happy to offer this minor contribution in any permissive license that would fit your project if needed.

Regards

David
