/// This macro will generate the tracker for the given structure.
/// ## Container Opts
/// - `crate_path`: A string which is the path to the `tinc` crate, by default `::tinc`
/// - `tagged`: Can only be used on enums to denote a tagged enum, default is false.
/// ## Field / Variant Opts
/// - `enum_path`: Forces the field to be treated as an enum, default is None.
/// - `oneof`: The field should be treated as a oneof.
