• Updated windows-sys to 0.61.
• Cache calls to std::thread::available_parallelism (#40).

This is a relatively large release, see #35 for more details.

• Epoch tracking has been removed, along with the Link, AsLink, and Collector::link API surface.
• The Deferred type has also been removed as a consequence of the removal of Link.
• The Clone implementation for Collector has been removed.
• Unprotected guards have been removed.
• Reclaimers now take *mut T, removing the need for type annotations when passing reclaimers to Collector::retire.
• Guard::belongs_to has been removed in favour of a Guard::collector accessor and Collector: PartialEq implementation.
• Reclaimers now receive a reference to the collector as their second argument.
• There are now protected RMW operations on the Guard trait, such as Guard::swap and Guard::compare_exchange.

• Fixed a bug where SeqCst protected loads were downgraded to Acquire on Windows, when the fast-barrier feature was enabled.

• Performance improvements.
• The fast-barrier feature flag enables runtime detection of fast memory barriers on Windows and Linux. It is enabled by default in this release.
• UnprotectedGuard is now #[non_exhaustive], preventing accidental guard usage that can lead to undefined behavior in safe code.

• Fixed a potential data race when using owned guards.

• Minor performance improvements.

• Minor performance improvements.

• Fix memory corruption bug when retire is recursively called during reclamation.
