not the prettiest but does work

hm wait i had another quick think, maybe we can just add a verbose version to call alternatively. should also technically help performance a miniscule amount

func process_script_verbose(path: String) -> String:
	var start_time := Time.get_ticks_msec()
	ModLoaderLog.debug("Start processing script at path: %s" % path, LOG_NAME)
	var processed := process_script(path)
	ModLoaderLog.debug("Finished processing script at path: %s in %s ms" % [path, Time.get_ticks_msec() - start_time], LOG_NAME)
	return processed
