file size information also with yt-dlp (also if video and audio separate stream are given) rather than total cache

Expected behavior of the wanted feature

As I open a youtube video, it will be expected to give the filesize of video (like yt-dlp -f 22), even if audio video stream are separate (yt-dlp -f=136+139) than it will be expected to show the audio and vidoe size separately.
It will be best to do it by mpv script, I don't find any mpv script related that I am trying to develop if you give some hint or to include in main mpv.

Alternative behavior of the wanted feature

What we have now -
As I used previous version of mpv, it will give the filesize information, even if with yt-dlp with one audio+video stream (like yt-dlp -f 22/18) it will give the total file size to download but there is no file size shown if combined audio-video (like yt-dlp -f 136+139) is played with mpv.
However as recent mpv replaced file size option with Total Cache when pressing i button

Start with the stats.lua and ytdl_hook.lua scripts shown in the log, then trace how the current Total Cache information is assembled for separate yt-dlp streams. Done should mean that pressing the information key shows video and audio sizes separately, and reports the combined size when appropriate.
