BgUtils yt-dlp Proof-of-Origin Token Provider Plugin

The `bgutil-ytdlp-pot-provider` is a Python plugin for `yt-dlp` (version 1.3.1) designed to generate and provide YouTube Proof-of-Origin (POT) tokens. This aims to bypass YouTube's 'Sign in to confirm you're not a bot' messages and 403 errors when using `yt-dlp` from flagged IP addresses. The plugin acts as an interface to an external POT generation service (either a Node.js/Deno HTTP server/script or a recommended Rust HTTP server/binary). The project is actively maintained with updates often tied to changes in YouTube's bot detection mechanisms.
