/// Helper macro for `FieldSet` createion with ease.
///
/// ### Example
///
/// ```rust
/// use fixed_width::{FieldSet, field, field_seq};
///
/// // Suppose field defined as:
/// let fields = FieldSet::Seq(
///     vec![
///         FieldSet::new_field(0..4).name("foo"),
///         FieldSet::Seq(
///             vec![
///                 FieldSet::new_field(4..6),
///                 FieldSet::new_field(6..8),
///             ]
///         ),
///     ]
/// );
///
/// // Which is identical to:
/// let fields_with_macro = field_seq![
///     field!(0..4).name("foo"),
///     field_seq![
///         field!(4..6),
///         field!(6..8),
///     ]
/// ];
///
/// assert_eq!(format!("{:?}", fields), format!("{:?}", fields_with_macro));
/// ```
