Three dependencies for Debian not present in instructions

[gmgauthier]

Just a quick one. I had to add the following to my fresh debian 11.3 install, to get the build with all the options on, to work:

sudo apt install libturbojpeg0-dev                                                                                                                                  
sudo apt install libexif-dev                                                                                                                                                                                               
sudo apt install libgraphicsmagick++1-dev    

Tried to submit the change to the REAME as a pull request, but can't push the branch.

The second line in the dependencies contains these ( https://github.com/hzeller/timg#get-dependencies-on-debianubuntu ). I think the slightly different names are just aliases within debian.

Did it not work with the latest Debian ?
