pipepipe-sabr: reconstructing YouTube SABR streaming

pipepipe-sabr reconstructs YouTube SABR/UMP streaming behavior from source-level analysis of PipePipe and implements a separate Python client. It handles segmented sessions, signature parameters, downloading and browser playback, with a protocol report mapping fields and a Node-based PO Token component. The author reports a complete 20-minute test download.
