Fixes #78.

Tested on Fedora Workstation 43 and Ubuntu Linux 25.10 (aarch64).

Why do you install gobject ? It is not used by OfdEdit. Or is it containing audioplayer and sounddevice libraries ? For a minimal installation it is better to install only the required libs.

If it is not installed, I get "No module named gi" on Fedora when running from source.

Strange, I retried with removing python3-gobject, and now it works. I'm removing it.

I also tested on Ubuntu, and unfortunately there, you have to recompile Pillow with Tk development headers, so the procedure is more complex, I'm adding this case.
