Added points_scale_factor option. This options allows you to pass a smaller version of the image you would like to store points for. Say you have a 10000x10000 image. If you pass this to pointsablbe, it will opperate very slowly. If you make a smaller version, say 1000x1000, you could pass this image to pointsable with a points_scale_factor of 0.10. Points saved to the pointsable object would be in the coordinate system of the bigger image
