Macro load_tailwind

macro_rules! load_tailwind {
    (always) => { ... };
    (always, $path:literal) => { ... };
    (jit) => { ... };
    () => { ... };
    ($path:expr) => { ... };
}

automaticly loads tailwind, depending on the config the macro should be called in the head to the html doc:

// example for maud

html! {
    (DOCTYPE);
    html {
        head {
            (load_tailwind!());
        }
        body {
            div."w-prose mx-auto" { "Tailwind just works" }
        }
    }
}

the actual way of loading the file depends on the compile mode (debug_assertions or not) in debug the compilation is skipped as to not slow down the build

calling load_tailwind!(jit) forces jit

calling load_tailwind!(always) has the same behaviour as include_html!(always) (never loads using Jit)
