including all functions that utilize this and nothing else. This allows developers to create constants using these functions as this is possible in normal ncurses

requires rust>=1.31 This might be a bit early as a lot of people are still on 1.29

Thank you! I'm all good with this requiring a newer version. The API is quite stable, so folks can stay on the older version until they're ready to upgrade Rust in order to use this.
