[youtube] Fix missing format details for 60fps DASH formats

Browse source 
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.
