algo/scroll: add center for centering the current col

ref #14027

@nemect is this what you wanted?

I guess? I would need to compile hyprland to test this. But these two questions would convince me :)

1. If i have three 50% columns with focus on first (third is hidden on right edge). Does center centers the first column? For my script this does work only for all other columns but first.
2. Does it work with direction:down?

If yes i would call this is exactly what i wanted and thank you very much for fast implementation. :)

well please do thats the point

I have compiled and tried. It does nothing. It correctly says ok after hyprctl dispatch so i believe it call the right switch case but windows stays the same.
