Remove a Rust binary

Usage:
    cargo uninstall [options] <spec>

Options:
    -h, --help                Print this message
    --root DIR                Directory to uninstall packages from
    --bin NAME                Only uninstall the binary NAME
    -v, --verbose ...         Use verbose output (-vv very verbose/build.rs output)
    -q, --quiet               Less output printed to stdout
    --color WHEN              Coloring: auto, always, never
    --frozen                  Require Cargo.lock and cache are up to date
    --locked                  Require Cargo.lock is up to date

The argument SPEC is a package id specification (see `cargo help pkgid`) to
specify which crate should be uninstalled. By default all binaries are
uninstalled for a crate but the `--bin` and `--example` flags can be used to
only uninstall particular binaries.
