Add array-based chunks and windows from slices

[cuviper]

pub trait ParallelSlice<T: Sync> {
    fn par_array_windows<const N: usize>(&self) -> ArrayWindows<'_, T, N>;
    fn par_array_chunks<const N: usize>(&self) -> ArrayChunks<'_, T, N>;
}
pub trait ParallelSliceMut<T: Send> {
    fn par_array_chunks_mut<const N: usize>(&mut self) -> ArrayChunksMut<'_, T, N>;
}

looks good!

My only hesitation is to wait for std stabilization: rust-lang/rust#74985 and rust-lang/rust#75027

Any update on when this pull request might be merged? I would love to use this for video format conversion.

I'm still hoping std will settle its API, so we can be consistent in how we replicate it here.

rust-lang/rust#74985 and rust-lang/rust#75027 were closed.

Right, but the first one (chunks) was closed as not planned, removed in rust-lang/rust#143289. I think the intention is that you can use slice::as_chunks or as_chunks_mut first, then iterate as normal. This ought to work with parallel iterators too, so maybe that's how we should leave it.

Rust 1.94.0 did stabilize array_windows though!

I published par_array_windows in rayon 1.12.0, and I'm going to close on chunks. If the standard library ever reconsiders, so can we. :)
