Document notify::event::EventAttributes::info

[bicarlsen]

It doesn't appear there is any documentation about what information notify::event::EventAttributes::info represents. e.g. What values are possible here? If info is Some("override"), what does this mean?

It seems there are only a few places info is set:

1. notify/notify/src/fsevent.rs

   Line 114 in 128bf62

   if flags.contains(StreamFlags::MUST_SCAN_SUBDIRS) {

2. notify/notify/src/fsevent.rs

   Line 159 in 128bf62

   if flags.contains(StreamFlags::IS_SYMLINK) {

3. notify/notify-debouncer-full/src/lib.rs

   Line 469 in 128bf62

   remove_event.event = remove_event.event.set_info("override");
