Expand description

Peels chained ModEx wrappers so codec/multitrack detection sees the underlying packet type. When a chain exceeds MAX_MODEX_CHAIN_LAYERS the payload is intentionally left wrapped and opaque: codec/multitrack detection derived from this payload (e.g. Conn::detected_video_codec / detected_audio_codec) will not fire for that frame. This is a deliberate CPU-amplification tradeoff, not a parsing bug — callers that surface detected-codec stats should expect them to be absent for such frames.
