Justin Wilson 8cdcdce326 craft-video: VP8 key-frame encoder (vp8-encode feature) (#969 )

Moves effectcraft's effectcraft-vp8enc here: the lossy picture of a WebP image
or animation frame, written from RFC 6386. Rate-distortion choice between the
16x16 and B_PRED intra modes, per-frame token probability updates, loop filter
level from the quantizer.

`vp8` now turns on `vp8-decode` and `vp8-encode`, as `vp9` does; the decoder's
tests and examples require `vp8-decode`. The tests decode the encoder's frames
with this crate's decoder: with the loop filter off it reproduces the encoder's
reconstruction exactly.

craft-video

Clean-room pure-Rust video codecs for the Craft apps, one feature per codec: DNxHD/DNxHR, VP8, ProRes and H.264.

Input and output are byte slices and planar sample buffers; the crate opens no files itself and performs no filesystem I/O.
Implemented from published standards and RFCs (SMPTE ST 2019-1, RFC 6386, SMPTE RDD 36 and ITU-T H.264).
Tested against ffmpeg as an external oracle with roundtrips, hostile fuzzing, and conformance vectors. No unsafe, no panics on corrupt streams. Builds for wasm32-unknown-unknown.
Containers (MP4/MOV, Matroska/WebM), bit-level I/O (craft_media::bitstream) and shared identifiers (CodecId, CodecParams) come from craft-media.

Cargo features

No codec feature is on by default.
