Proxy support

This looks awesome but it doesn't seem to work behind a proxy.
Could it take into account common proxy env vars? (http_proxy, https_proxy, HTTP_PROXY, HTTPS_PROXY, ALL_PROXY NO_PROXY)

Hey, no, it might not work or everything even though I add this. It will just work for the HTTP client that handles streaming. Some things are going through external libraries like the yt-dlp.
