Strip away copyrighted ICC profiles

Hi,

While checking for embedded non-free ICC profiles, the following files showed up. The proposed alternative files just remove the embedded possibly non-free and anyway useless ICC profiles:

    exiftool -icc_profile"-<=" $files

The images have been checked identical to their original, just a lot smaller in size, without the binary data “Copyright (c) 1998 Hewlett-Packard Company”.

Those files (and the README) were executable, the second commit fixes that too.

Regards

David
