py-lazy-object-proxy: updated to 1.6.0

1.6.0 (2021-03-22)
------------------

* Added support for async special methods (``__aiter__``, ``__anext__``,
  ``__await__``, ``__aenter__``, ``__aexit__``).
  These are used in the ``async for``, ``await` and ``async with`` statements.

  Note that ``__await__`` returns a wrapper that tries to emulate the crazy
  stuff going on in the ceval loop, so there will be a small performance overhead.
* Added the ``__resolved__`` property. You can use it to check if the factory has
  been called.
