Use :orig instead of :large in TwitterRipper

This patch will allow TwitterRipper to download the original image instead of the resized large image

Normal image (600×300) → https://pbs.twimg.com/media/CCiZIc-WgAAc9vx.jpg
Large image (1024×512) → https://pbs.twimg.com/media/CCiZIc-WgAAc9vx.jpg:large
Original image (1280×640) → https://pbs.twimg.com/media/CCiZIc-WgAAc9vx.jpg:orig
