[Feature request] choose display

[kaliiiiiiiiii]

and pass it onward in __ainit__ to os base (linux.py) and use this display string as the display_env if set

    def __init__(self, pid: int, scale_factor: float, displayStr: Optional[str] = None) -> None:
        self.pid = pid
        self.scale_factor = scale_factor
        self._loop = asyncio.get_event_loop()

        display_env = displayStr or os.getenv("DISPLAY")
        self.display = display.Display(display_env)
        self.tab_pid = self.get_window()

For multiple XVFB//X11 displays, or pseudo-headless
