/// Macro to delegate methods to a specified field
///
/// This macro generates methods that delegate to methods on a field of the struct.
/// Each delegated method will call the corresponding method on the specified field
/// and return `self` for method chaining.
///
/// # Example
///
/// ```rust,ignore
/// use docx_rs::delegate_to_field;
///
/// struct Wrapper {
///     inner: SomeType,
/// }
///
/// impl Wrapper {
///     delegate_to_field! {
///         inner =>
///         method1(param: i32) -> Self,
///         method2(a: String, b: bool) -> Self,
///         method3() -> Self,
///     }
/// }
/// ```
