[youtube] Extract formats from multiple DASH manifests (Closes #6093)
DASH manifest pointed by dashmpd from the video webpage and one pointed by get_video_info may be different (namely different itag set) - some itags are missing from DASH manifest pointed by webpage's dashmpd, some - from DASH manifest pointed by get_video_info's dashmpd). The general idea is to take a union of itags of both DASH manifests (for example video with such 'manifest behavior' see https://github.com/rg3/youtube-dl/issues/6093).
