[youtube] Fix missing format details for 60fps DASH formats
60fps DASH formats do not appear in the DASH manifest, but the non-DASH video info page does contain additional parameters for DASH formats that we can parse. Use those when they exist. This fixes "bestvideo" not selecting 60fps formats over similar 30fps formats just because the file size is unknown.main
