layers/meta-opentrons: add rust 1.71.1

Or more specifically cargo and everything that depends on, since maturin
uses cargo.toml features that need a new version

+## Introduction
+
+This provides the Rust compiler, tools for building packages (cargo), and 
+a few example projects.
+
+## Building a rust package
+
+When building a rust package in bitbake, it's usually easiest to build with
+cargo using cargo.bbclass.  If the package already has a Cargo.toml file (most
+rust packages do), then it's especially easy.  Otherwise you should probably
+get the code building in cargo first. 
+
+Once your package builds in cargo, you can use
+[cargo-bitbake](https://github.com/cardoe/cargo-bitbake) to generate a bitbake
+recipe for it.  This allows bitbake to fetch all the necessary dependent
+crates, as well as a pegged version of the crates.io index, to ensure maximum
+reproducibility. Once the Rust SDK support is added to oe-core, cargo-bitbake
+may also be added to the SDK.
+
+NOTE: You will have to edit the generated recipe based on the comments
+contained within it
+
+## Pitfalls
+
+ - TARGET_SYS _must_ be different from BUILD_SYS. This is due to the way Rust
+ configuration options are tracked for different targets. This is the reason 
+ we use the Yocto triples instead of the native Rust triples. See rust-lang/cargo#3349.
+
+## Dependencies
+
+On the host:
+ - Any `-sys` packages your project might need must have RDEPENDs for
+ the native library.
+
+On the target:
+ - Any `-sys` packages your project might need must have RDEPENDs for
+ the native library.
