- ac3: LFE channel taken without `expect`.
- audio-dsp: the channel matrix match is exhaustive (no `unreachable!`); an unknown internal
parameter reads as 0 (debug-asserted) instead of `panic!`.
- opus: dual-stereo bands and SILK frames take the optional buffer / range decoder with `if let`.
- mpeg2v: 64-bit peek through `get()` + `first_chunk`; the literal VLC table parser no longer
panics (debug-asserted).
- prores, dnx: IDCT rows through `as_chunks`; ProRes block store and alpha slices without
unwrap/expect; DNx header timecode through `get()`.
- dnx: `Encoder::new` returns `Result` instead of panicking on a raster the profile can't code
(e.g. 0x0), with a regression test; missing CID table is an error.
- Each crate denies unwrap/expect/panic/unimplemented/todo/unreachable outside tests.
