/// Katakana.
///
/// # Example
///
/// ```
/// use to_kana::to_kana;
///
/// assert_eq!(
///     "ひらがな and カタカナ",
///     to_kana!("{:H} and {:K}", "hiragana", "katakana").unwrap()
/// );
/// ```
///
/// # Supported formats
/// - `:H` => Hiragana (ひらがな)
/// - `:K` => Katakana (カタカナ)
/// - `:K/2` => Half-width Katakana (ｶﾀｶﾅ)
/// - `:h` => Small Hiragana (ぁぃぅぇぉゃゅょっ)
/// - `:k` => Small Katakana (ァィゥェォャュョッ)
/// - `:k/2` => Small, Half-width Katakana (ｧｨｩｪｫｬｭｮｯ)
