- update to 1.9.0:
* Added support for matrix multiplication operator (``@``).
* Should have all the wheels now (including the manylinux
ones).
* Bumped minimum version requirements for setuptools and
setuptools-scm.
* Switched the default pure python fallback implementation to
the "simple" one (when you ``from lazy_object_proxy import
Proxy`` and the C extension is not available).
Previously the "slots" implementation was used but as it
turns out it is slower on Python 3.
