Fuchsia is doing an audit of chrono 0.4.34, and we noticed an unncessary unsafe of `Send` for `DateTime`. While it's valid since `Tz::Offset` is `Send`, and `NaiveDateTime` only has `u32` fields, there's a potential hazard if `NaiveDateTime` ever grows unsendable fields (unlikely as that is). This (and the `Copy` impl) were added 9 years ago to fix chronotope#25, which stemmed from early versions of associate traits not working properly with auto-traits. This has since been fixed, and is no longer necessary with the MSRV 1.61.0.
