Windows build

[dagewa]

I'm working through Windows build errors on this branch (see https://hackmd.io/510HFFicQ7-6yYSUXqHq-A). Still have more to fix, but I wanted to make this visible early (particularly to @Anthchirp), in case there are better approaches. First issue, need this otherwise import ssl fails down the line.

This SSL issue was with the windows store version of python, right?

No, it's in the subprocess calls to the executable defined as conda_python

It turns out that adding conda's DLL directory to PATH during the build was enough to get through with the set up described. There are still many test failures, but I'd rather handle them separately, so marking this as ready now.

@dagewa could you have a look if this works for you?

@Anthchirp thanks, can confirm the build works for me.
