preview_images_method sixel

Is your feature request related to a problem? Please describe.
Ueberzug is abandonware, and it does not work on wayland.

Describe the solution you'd like
Implementing sixel instead (or along with) Ueberzug.

Additional context
This month sixel support was finally merged on ranger, bringing image preview on ranger to wayland compositors. If you wanna test it, you need the package 'sixel', a sixel compatible terminal (foot, for example, but it is an standar), and then set this on your ranger.rc

set preview_images_method sixel

You may also need ranger-git at this point.

Note that this is a very low priority improvement, as one does not normally need image preview while on vim/neovim.

You can install ueberzugpp. I don't use sixel so I can't help with this issue.
