docs: Generate the byte code of a transformed parser class
  
  <p>When you create a parser using {@link
  #createParser(Class, Object...)}, Parboiled generates a new class which
  is the one you actually use for parsing. This method allows to get the
  byte code of such a generated class in a byte array.</p>
  
  @param parserClass the parser class
  @param <P> class of the parser
  @param <V> see {@link BaseParser}
  @return the byte code
  
  @throws RuntimeException byte code generation failure
