Add PyAV (av>=16.0.0,<16.1.0) for faster video frame seeking. Benchmark shows 7.4x speedup for random seeks vs OpenCV on Linux. Refs #845
Benchmark now compares three strategies: - OpenCV exact: 73 fps - PyAV keyframe: 540 fps (7.4x faster) - PyAV exact: 160 fps (2.2x faster) Two-tier strategy validated: even exact seeking beats OpenCV. Refs #845
