Add proxy argument

[itsNikolay]

Could you add --proxy URL argument to yt-dlp command ?
Probably it can be specified via ENV variable PROXY_URL
Its reference is here: https://github.com/yt-dlp/yt-dlp?tab=readme-ov-file#network-options

Thanks four your amazing work! ❤️

Also it would be nice to have ability to pass remain arguments

you can now set the MR_PROXY environment variable.

I'll try to come up with something so that all arguments can be passed. Thanks for the suggestion!

Made an update. You can now either set the MR_PROXY environment variable or set the arguments in the request URL. For example ?url=example.com&--proxy=foo. You can now supply any argument in the URL and it'll be passed down to yt-dlp

This is fine for the API endpoint, but outside of editing the URL manually for the main UI, I'll eventually need to add a UI component to set the arguments
