pypi entry outdated. Update or change installation instructions.

pypi entry points to release 0.4.2. It misses changes, e.g. related to #55 and is thus not compatible with the QCoDeS version >= 0.40.0.

Can (and should) previous releases specify up to what version of the dependencies they function? This would be relevant for data management, but can be replaced by the convention that for reconstructing data analysis etc., always the earliest compatible version of dependencies is used.
