vo_sixel: change default dither to "auto"HEADmaster
For two reasons: 1. It was counter intuitive that there's an "auto" value (which is actually a libsixel value and not an mpv one), but it's not the default value - our default was Atkinson. 2. "auto" provides better dithering than Atkinson with libsixel, which is especially noticeable with smooth gradients - where Atkinson has visible banding. In libsixel 1.8.2 the "auto" value maps to Atkinson if the output palette has up to 16 colors, or to Floyd-Steinberg otherwise (e.g. using fixed palette with 256 colors chooses Floyd-Steinberg).
