feh: update to 3.8

Mon, 03 Jan 2022 11:29:03 +0100  Daniel Friesel <derf+feh@finalrewind.org>

* Release v3.8
    * Add button ID "0" to cursor bindings. This pseudo-button is triggered
      whenever feh observes a cursor movement. It does not have a default
      binding.
    * Support hexadecimal IDs in --window-id
    * Disable --auto-rotate in feh builds compiled with Imlib2 1.7.5 or later.
      Imlib2 1.7.5 introduces transparent EXIF-based image orientation
      adjustment, so --auto-rotate is no longer needed (and would cause
      mis-orientation of images, as Imlib2 has already adjusted the
      orientation).
