Binary releases for bar-rs

• Alpine (see the Containerfile)
• Arch (see the Containerfile)
• Debian (see the Containerfile)

Used the following podman commands to run the containers:

cd $PATH_OF_DIR_WITH_CONTAINERFILE
podman build -t bar-rs-compile .
podman run --rm --network none -v $PWD:/out bar-rs-compile
