Let me know if I should add these to the `Cargo.toml`.
All `cargo test` tests pass on the latest x86_64-unknown-linux-gnu
nightly.

#719 is failing tests due to requiring a newer version of rust than we
currently specify. This PR updates to 1.85.1 and sets the edition to
2024.
I've also updated dependencies and runner images, using the ubuntu arm
runner which removes the need for qemu and other hacks.
Closes#719.
Two key changes here:
- Removed some defunct reduction benches and added some more alpha
reduction benches.
- Changed use of `chunks()` to `chunks_exact()` where appropriate to
improve performance. (As a byproduct, this also fixes a potential crash
if a malformed file has a PLTE chunk that isn't a multiple of 3.)
If no palette reduction occurred (or palette reductions were off), a
fully transparent palette entry may not have been zeroed to black. By
ensuring this gets cleaned in the `indexed_to_channels` transformation,
we may able to achieve a grayscale conversion that would otherwise have
been RGB.
This is the final piece of the puzzle in #649 to achieve better file
sizes on the first run and avoid further changes on a second run.
Results from the images in #649 (combining this PR and #673):
