zoom window and restore view

[masriomarm]

when working with multiple windows, zoom a certain window and restore splits as it was when done. same like zooming tmux pane.

• I think 3 commands will be useful

1. fully zoom window - almost like close windows except current but being able to restore the view.
2. vertical expand window - to expand window vertically and restore view later.
3. horizontal expand window - to expand window horizontally and restore view later.
