add usenetrc argument for ydl_opts to allow the oauth plugin to work.

[111100001]

see https://github.com/111100001/tubeup oauth plugin: https://github.com/coletdjnz/yt-dlp-youtube-oauth2

some yt-dlp users might get their ip blacklisted and youtube will show "Sign in to confirm you’re not a bot. This helps protect our community. Learn more" error

a workaround for this issue is using a yt-dlp plugin (plugin link above)

the argument will have no effect and will be ignored if the ~/.netrc config file does not exist
