Update pugiXML library

Release highlights:

xml_attribute::set_value, xml_node::set_value and xml_text::set now have overloads that accept pointer to non-null-terminated string and size
Fix error handling in xml_document::save_file that could result in the function succeeding while running out of disk space
Fix memory leak during error handling of some out-of-memory conditions during xml_document::load
