[New Port Request] czkawka - duplicate finder

[IronCraftMan]

​https://github.com/qarmin/czkawka a duplicate finder whose main features are more or less the ability to find non-exact duplicates of images and videos.

Czkawka currently requires GTK4 to be installed via homebrew, which doesn't work with older versions of OS X. Would be nice if it could be installed using the gtk4 port, which supports older systems.

I have a PR building this that is pretty much ready to go: ​https://github.com/macports/macports-ports/pull/22350

Only issue is that the GUI is failing to start:

19:01:15.632 [INFO] czkawka_core::common: Czkawka version: 6.1.0, was compiled with release mode

(czkawka_gui:23100): Gtk-WARNING **: 19:01:15.664: Unable to acquire the address of the accessibility bus: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.a11y.Bus was not provided by any .service files. If you are attempting to run GTK without a11y support, GTK_A11Y should be set to 'none'.
No provider of glGenSamplers found.  Requires one of:
    Desktop OpenGL 3.3
    GL_ARB_sampler_objects
    OpenGL ES 3.0
[1]    23100 abort      ./work/destroot/opt/macports-test/bin/czkawka_gui

So we can commit it now and patch to fix the OpenGL problem for the GUI later on.
