New CamiTK 5.2.0 release

[Emmanuel Promayon <Emmanuel.Promayon@univ-grenoble-alpes.fr>]

    Dear all,
    
    First of all, I'd like to wish the whole team a great sprint in
    Berlin.
    
    As far as CamiTK is concerned, version 5.2.0 has been released
    upstream and I have updated the package on salsa.
    I did not tag the master branch with the debian/5.2.0 tag, as I am
    not 100% sure that everything is valid.
    The pristine-tar branches were updated this time (hopefully the
    right way!).
    
    If you can spare sometime between two bug fixing, could someone
    please have a look and let me know if there is any problem (or
    tag+upload if everything seems correct!) ?
    
    Thank you in advance for your comments and help.
    
    Best regards,
    Emmanuel
