nx_webpprobe.nx -- DIAGNOSTIC: which WebP variant is actually on the wire?
Our webp_decode() searches for the VP8L (lossless) fourcc and returns 0 for anything else, so wiring it
in blind would fix an unknown fraction of the gap. RIFF layout: 'RIFF' <size> 'WEBP' <fourcc> -- so the
variant is bytes 12..15. This walks a directory and reports the split, which decides whether closing the
WebP gap is a WIRING job (VP8L) or a CODEC job (VP8 lossy intra).
