feat: Expand and Shrink keybinds

[Clichas]

(1) Description

While i love this extension i can't get hold of the resize/increase keybinds, we could have something close to Expand/Shrink active window:
For example if my active window is the left one expanding it will make it grown in size to the right and shrink will bring it back to the left(while adjusting the left side windows).
Same can work for down and up, if my active window is the bottom one it will expand up and so on.
This is close to what is implemented in Amethyst tilling window for macos.
