        Perform click (touch, tap, etc.) action on target device at given coordinates.

        The coordinates (x, y) are either a 2-list or 2-tuple. The coordinates values for x and y must be in the
        interval between 0 ~ 1 to represent the percentage of the screen. For example, the coordinates ``[0.5, 0.5]``
        represent the `center` of the screen and the coordinates ``[0, 0]`` represent the `top left corner`.

        See ``CoordinateSystem`` for more details about coordinate system.

        Examples:
            Click the point of ``(100, 100)`` of screen which resolution is ``(1920, 1080)``::

                poco.click([100.0 / 1920, 100.0 / 1080])
