What's Changed

• Add new Sys trait to allow abstracting over the underlying filesystem. Particularly useful for wasm32-unknown-unknown targets. Thanks @dsherret for this contribution to which!
• Add more debug level tracing for otherwise silent I/O errors.
• Call the NonFatalHandler in more places to catch previously ignored I/O errors.
• Remove use of the either dependency.
