[dependabot]

Bumps rayon from 1.7.0 to 1.8.1.

Changelog

Sourced from rayon's changelog.

Release rayon 1.8.1 / rayon-core 1.12.1 (2024-01-17)

• The new "web_spin_lock" crate feature makes mutexes spin on the main browser thread in WebAssembly, rather than suffer an error about forbidden atomics.wait if they were to block in that context. Thanks @​RReverser!

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.
