FilmCraft's crates/apv at 4bec22bd moves to craft_video::apv: the decoder
(craft_video::apv::decode, feature `apv-decode`), the encoder
(craft_video::apv::encode, feature `apv-encode`), both re-exported at the
module root; `apv` turns on both. Sources, README and tests (ffmpeg oracle,
alpha, mutation and hostile sweeps).
Changes in the move: craft_media::bitstream and craft-media-testkit instead of
FilmCraft's, one test target (tests/apv), crate paths.
New: DecodeOptions::memory_budget (craft_video::budget) refuses a frame whose
samples do not fit before anything is allocated (Error::MemoryBudget).
Fixed, each with a test that fails without it (debug-build overflows):
- EncoderConfig::new multiplied width, height and 30 in u64 without a check.
- Frame::new shifted by the bit depth unchecked (32 and above overflow).
- The public transform functions shifted by a bit depth outside 10..=16.
