/// Macro to generate boilerplate EventParser implementation for protocol parsers
///
/// This macro eliminates the repetitive code where each parser simply delegates
/// all EventParser trait methods to its inner GenericEventParser.
///
/// Usage:
/// ```rust
/// impl_event_parser_delegate!(MyEventParser);
/// ```
///
/// This will generate the complete EventParser implementation that delegates
/// all methods to `self.inner`.
