RUSTSEC-2020-0113 AtomicOption should have Send + Sync bound on its type argument.

In the affected versions of this crate, AtomicOption unconditionally implements Sync. This allows programmers to move non-Sync types across thread boundaries e.g. Rc, Arc, which can lead to data races and undefined behavior. It is also possible to send non-Send types like std::sync::MutexGuard to...
