/// The input value is mapped from -100..100 to -180..180 degrees.
///
/// # Arguments
///
/// * `image` - A reference to the input [DynamicImage].
/// * `value` - The hue rotation value, typically between -100.0 and 100.0.
///
/// # Returns
///
/// A new [DynamicImage] with the hue rotation applied.
///
/// # Examples
///
/// ```no_run
/// use hdim_core::adjustments::hue::apply_hue;
/// use image::DynamicImage;
///
/// let img = DynamicImage::new_rgba8(100, 100);
/// let adjusted = apply_hue(&img, 50.0);
/// ```
