trillium-http-v1.2.2

Added

• Error::Other and the Error::other(impl Error) constructor — a catchall variant for application-level errors that need to flow through trillium_http::Result.
• KnownHeaderName::CdnCacheControl

Changed

• From<ReceivedBody<'static, _>> for Body now propagates trailers from
  the source body through the conversion. Behavior change for the
  trailer-carrying case; equivalent for bodies without trailers.
