feat (hyprbars) : Have mouse event handling

[kRHYME7]

Is it possible for hyprbar to handle mouse event?

Example: left_click => right_click => middle_click => scroll_up => scroll_down => double_left_click =>

If not, should still be fine as this is a tiling WM/Compositor after all. What I only missed with the bar is the double click to make the window in full-screen.

Thanks!
