Bump av-metrics-decoders in other av-metrics crates

[FreezyLemon]

These are breaking changes[^1] because the Y4MDecoder type is exposed in the API (and got changed in av-metrics-decoders). The changes are pretty simple otherwise. I wanted to update some dependencies, but this should be done first I think

[^1]: Nevermind. The tests project is obviously not published/versioned and I'm not sure what compatibility guarantees the av-metrics-tool is supposed to make.

New clippy errors. I opened #299 to fix those.

Looks like the other crates finally build again :tada:

The history has gotten a bit mangled here. Basically, I updated ffmpeg-the-third to 2.X in the decoders crate and bumped it in the -tests and -tool crate.

After this, both -decoders and -tool need a new crates.io release. I don't have the permissions for these packages.

Thanks, I'll get a release out later today.
