rusty_av2d 0.3.0: A Faster Rust AV2 Decoder

rusty_av2d 0.3.0 is a Rust AV2 decoder, 2.7 to 3.8 times faster than 0.2.13 on two clips, byte-identical to AVM, and not a claim against libavm.

Mercury Counters: Less Memory Traffic, No Verified Speedup Yet

Mercury counters show ASR memset falling from 573.3 MB to 3.3 MB and KV copies from 510.0 MB to 14.4 MB. Timing was inadmissible, so no speedup is verified yet.

rusty_h265 0.7.0: Nine Decoder Veins and a Mixed FFmpeg Result

rusty_h265 0.7.0 cut decoder instructions 26 to 37 percent on three inputs and decodes 1.37x to 1.50x faster than 0.6, while ordinary 8-bit inter still trails FFmpeg.
