Migrate to Rust 2024 and to iced 0.14.

@Joylei with the 2024 edition of Rust, static mutable refs are unstable.

I had to use #[allow(static_mut_refs)] on method style_to_font if you want to take a closer look.

I've published plotters-iced2 for you to use with the latest versions of iced, Since the maintainer of this library seems to be inactive on GitHub.
