Command Categories/Utilities

Would be nice to get another package which extends this one e.g. `@rbxts/centurion-utilities`. or could just add-on to this one. This package would include useful tools like ```ts @Category<T = string>(data: T) ``` This idea was taken from [discordx](https://www.npmjs.com/package/@discordx/utilities) that has this similar behavior, and I use it to differentiate the command ranks, would be extremely nice to get a similar implementation.
