A helper tool for sending/receiving MQTT payloads over stdin/stdout

Requirements:

• CMake
• Ninja or GNU Make
• eclipse-paho-mqtt-c library

or use the Nix flake.

Ninja build system is recommended, but not required, GNU Make should be fine.

Cross-compiling works with RoboCon brains if you use static libraries (default if available). Using shared libraries probably won't work because of version mismatches. You will also need a static libc, probably musl.

...or use the Nix flake to handle this for you, use cross-aarch64-linux for brains. All cross targets are defined as static here.

Use clang-format for code formatting
