///
/// - Parameters:
///   - imageToCrop: The image to be cropped.
///   - maskShape: The shape of the mask used for cropping.
///   - configuration: The configuration for the cropping behavior. If nothing is specified, the default is used.
///   - onComplete: A closure that's called when the cropping is complete. This closure returns the cropped `UIImage?`.
///     If an error occurs the return value is nil.
