Subject: [PATCH] Specify the MSRV in the Cargo.toml

This will be stabilized with Rust 1.56, see
* https://github.com/rust-lang/rust/issues/65262
* https://github.com/rust-lang/cargo/pull/9732

For older cargo versions, this will print a warning, but will not fail
the build/check/test.
