message: Temporary fix for typed-arena version regression
  Due to a Rust [version regression in `typed-arena`](https://github.com/SimonSapin/rust-typed-arena/issues/31) we can now only support Rust 1.36.  This adds a temporary minimum version of Rust 1.36, and allows failures for Rust 1.32 until this is resolved.
