add support for returning type of urllib.parse.ParseResult

[albertedwardson]

Could resolve #2

Performance impact:
Yes, using namedtuple + acquiring scheme, netloc, path, params, query, fragment at creation time reduces performance slightly, but this implementation is still significantly faster than urllib.parse.

TODOs: ?

• Add tests to ensure parse_compat matches urllib.parse.urlparse results
• Consider adding ParseResultBytes and other result types
• Explore cleaner approaches for the compatibility layer (without? introducing Cython)
