gocui plugin refactor to a *node binary tree

    rename arg '--gui <toolkit>'
    add a cloudflare example
    fixes since go v1.21 didn't compile anymore due to argv order
    more place() changes
    recursive size computation

    gocui: Major refactor to use the *node binary tree
    gocui: refactor place() and size()
    gocui: better place() and spacing (tab, buttons, etc)
    gocui: better mouse click handling
    gocui: switch to using tk.gocuiSize & tk.size
    gocui: event handling cleanups
    gocui: add window labels work
    gocui: struct cleanups
    gocui: duplicate binary tree structs removed
    gocui: deprecate old children
