vo_sixel: re-fit image on terminal resize 

The obvious approach would be SIGWINCH, however, integrating it would
be tricky, so instead we simply poll the size on draw_frame.

This means the image won't resize automatically when still - e.g.
cover art or when paused, though it would re-fit on OSD changes.
