Releasing CLI tool on its own

[raszi]

It would be great to have the sample CLI tool on its own, so it could be used in other CLI tools.

What kind of functionality would you imagine such a CLI tool would have?

[raszi]

Something similar to st, it would receive a number on its input and display the histogram on its output.

That seems like a great idea! I'd be happy to take a look at a PR.

Unfortunately, I am not proficient in Rust, so I won't be able to provide a PR.
