Suggestion: Add categories ”no_std“ and maybe “embedded” to Cargo.toml

Hi,

it would be great if you could add the category "no-std" (and maybe also "embedded") to the Cargo.toml file of your crate. Adding these categories would make it a lot easier to find for embedded developers on crates.io using filter by category. Right now, your crate is excluded from the filtered results despite being compatible.

It would look like this:

[package]
categories = ["no-std", "embedded"]

Agreed, I'll add later today or tomorrow and publish with #17 all going well

I've looked through all the category slugs and the two here seem like the most fitting. Maybe algorithms could count as well because this controller is fundementally an algorithm?
