Allows for easy manipulation of debug formatting through a derive macro

```rust

use smart_debug::SmartDebug;

use std::fmt;

#[derive(SmartDebug, Default)]

#[debug(skip_defaults)]

struct Text {

    #[debug(no_skip)]

    text: &'static str,

    #[debug("0x{:06x}")]

    color: u32,

    #[debug(wrapper = DebugInline)]

    hyperlink: Option<&'static str>,

    is_bold: bool,

    is_italics: bool,

}

// Wrapper that displays inline even when using pretty formatting (`{:#?}`)

struct DebugInline<'inner, T>(pub &'inner T);

impl fmt::Debug for DebugInline<'_, T> {

    fn fmt(&self, f: &mut fmt::Formatter<'_>) -> fmt::Result {

        f.write_fmt(format_args!("{:?}", self.0))

    }

}

const HYPERLINK: &str = r#"

Text {

    text: "Look! A link",

    color: 0x005cc5,

    hyperlink: Some("https://example.org"),

    is_italics: true,

    ..

}

"#;

fn main() {

    let hyperlink = Text {

        text: "Look! A link",

        hyperlink: Some("https://example.org"),

        color: 0x00_5c_c5,

        is_italics: true,

        ..Text::default()

    };

    let formatted = format!("\n{hyperlink:#?}\n");

    assert_eq!(formatted, HYPERLINK);

}

```
