Usage of set_params_from_dict fails

[Glonks]

When using the new feature to set params from a dict, the node fails with the following error:

NameError: name 'unpack_parameter_dict' is not defined

I think the error comes from here:

generate_parameter_library/generate_parameter_library_py/generate_parameter_library_py/jinja_templates/python/parameter_library_header

Lines 57 to 80 in 28b1870

	@staticmethod
	def unpack_parameter_dict(namespace: str, parameter_dict: dict):
	"""
	Flatten a parameter dictionary recursively.
	:param namespace: The namespace to prepend to the parameter names.
	:param parameter_dict: A dictionary of parameters keyed by the parameter names
	:return: A list of rclpy Parameter objects
	"""
	parameters = []
	for param_name, param_value in parameter_dict.items():
	full_param_name = namespace + param_name
	# Unroll nested parameters
	if isinstance(param_value, dict):
	nested_params = unpack_parameter_dict(
	namespace=full_param_name + rclpy.parameter.PARAMETER_SEPARATOR_STRING,
	parameter_dict=param_value)
	parameters.extend(nested_params)
	else:
	parameters.append(rclpy.parameter.Parameter(full_param_name, value=param_value))
	return parameters
	def set_params_from_dict(self, param_dict):
	params_to_set = unpack_parameter_dict('', param_dict)

The method is not referred to via self, and so python fails to find it.

Testing locally, simply removing @staticmethod and adding self seems to solve the issue.
