Update rayon-core requirement from =1.10.0 to =1.12.0

[dependabot]

Updates the requirements on rayon-core to permit the latest version.

Changelog

Sourced from rayon-core's changelog.

Release rayon 1.8.0 / rayon-core 1.12.0 (2023-09-20)

• The minimum supported rustc is now 1.63.
• Added ThreadPoolBuilder::use_current_thread to use the builder thread as part of the new thread pool. That thread does not run the pool's main loop, but it may participate in work-stealing if it yields to rayon in some way.
• Implemented FromParallelIterator<T> for Box<[T]>, Rc<[T]>, and Arc<[T]>, as well as FromParallelIterator<Box<str>> and ParallelExtend<Box<str>> for String.
• ThreadPoolBuilder::build_scoped now uses std::thread::scope.
• The default number of threads is now determined using std::thread::available_parallelism instead of the num_cpus crate.
• The internal logging facility has been removed, reducing bloat for all users.
• Many smaller performance tweaks and documentation updates.

Release rayon 1.7.0 / rayon-core 1.11.0 (2023-03-03)

• The minimum supported rustc is now 1.59.
• Added a fallback when threading is unsupported.
• The new ParallelIterator::take_any and skip_any methods work like unordered IndexedParallelIterator::take and skip, counting items in whatever order they are visited in parallel.
• The new ParallelIterator::take_any_while and skip_any_while methods work like unordered Iterator::take_while and skip_while, which previously had no parallel equivalent. The "while" condition may be satisfied from anywhere in the parallel iterator, affecting all future items regardless of position.
• The new yield_now and yield_local functions will cooperatively yield execution to Rayon, either trying to execute pending work from the entire pool or from just the local deques of the current thread, respectively.

Release rayon-core 1.10.2 (2023-01-22)

• Fixed miri-reported UB for SharedReadOnly tags protected by a call.

Release rayon 1.6.1 (2022-12-09)

• Simplified par_bridge to only pull one item at a time from the iterator, without batching. Threads that are waiting for iterator items will now block appropriately rather than spinning CPU. (Thanks @​njaard!)
• Added protection against recursion in par_bridge, so iterators that also invoke rayon will not cause mutex recursion deadlocks.

Release rayon-core 1.10.1 (2022-11-18)

• Fixed a race condition with threads going to sleep while a broadcast starts.

Release rayon 1.6.0 / rayon-core 1.10.0 (2022-11-18)

• The minimum supported rustc is now 1.56.
• The new IndexedParallelIterator::fold_chunks and fold_chunks_with methods
