   Decoalesces events that are collapsed by kevent(2). Sometimes events like NOTE_EXEC and NOTE_FORK will arrive in one event, and we'd only surface one

   Adds:

   • Decoalesces events that are collapsed by kevent(2). Sometimes events like NOTE_EXEC and NOTE_FORK will arrive in one event, and we'd only surface one of them. Now, we surface both. This comes with the side effect that we will sometimes surface events the user didn't necessarily ask for, since bundled events will be bundled if only one of the filter flags was passed in.
   • Reduced code size in add_filename/remove_filename
   • Vnode is now comparable
   • Added Truncate support on OpenBSD
   • Added Trackerr support on all platforms

   Remove all panics, returning errors instead

   Adds:

   • Bump kqueue-sys to 1.1.1
   • Handle NOTE_READ on FreeBSD
   • Better documentation of errors
   • Add fd-based benchmarks

   Fixes:

   • Remove all panics, returning errors instead
   • Do not close File or fd's on drop, since we do not own them
   • Vnode::Extend has nothing to do with truncate(2)
   • Allow removal of non-utf8 pathnames (although imperfect)
   • Remove a bunch of unchecked casts and fail if data is out-of-range
   • from_error, is_err, poll, poll_forever and iter are #[must_use]
   • Internally use OwnedFd to track our kqueue object
   • Ident.PartialEq did not compare enum discriminants
   • Track watches in a HashMap, leading to much faster remove_* performance
   • Preallocate internal vec when watching objects, reduces memory usage and increase perf
   • Fast fail returning events from unstarted Watchers
   • Don't unconditionally declare ourselves as started
   • Don't include drops in benchmark results
