A small hacky utility for setting the version of a Rust crate to 0.0.0.

I use this for optimising build-times in Docker, avoiding having to recompile dependencies when bumping the crate version.

It currently works by simply setting package.version in Cargo.toml, as well as setting package.<name>.version in Cargo.lock (where <name> is the package.name value in Cargo.toml).
