Copyright holder for the contents of the header should be specifiable

[Angus-Bethke-Bachmann]

As a user of the header generator, I would like to be able to specify that I am the copyright holder of the generated contents.

/*****************************************************************************
 * Copyright (c) 2026 Angus Bethke                                           *

#ifndef _HEADERS_MYCOOLINTERFACE_
#define _HEADERS_MYCOOLINTERFACE_

#include <stdint.h>
#include <stdbool.h>
#include <math.h>
#include <time.h>
#include <dependencies.plc.h>

....

I would expect this to be an optional parameter as part of the generation process, and if none is supplied, no copyright information will be present in the header at all.
