AttributeError: There is no sdist package on pypi for lets-plot.

We are working on Anaconda distribution and at the moment are a bit stack with an error when building a Windows wheel, see issue Unable to use MinGW instead of MSVC for building packages on Windows. The situation is uncertain so far.
