A long time issue with Selene on Windows is that, due to having MSVC bindings, installation is not straightforward; users first need to ensure that they have MSVC runtime libraries available on their system. These can only be distributed by Microsoft.
MinGW, on the other hand, is open source, and is freely available. We can bundle its standard library libstdc++-6.dll with selene (due to the GCC Runtime Library Exception of GPL). The user needs to do nothing - just pip install selene_sim and they're off to the races.
Recently we've been getting build failures in windows CI due to a conflict between mingw and msvc, which appears to be due to a windows worker update. It seems like a good opportunity to get this MSVC pain out of the way.
This was my first PR crafted with the github copilot action. It took some guiding, but it ended up as something that is workable in CI, and on a windows machine without msvc installed, including testing proprietary plugins to ensure that they aren't impacted by this change. It's likely some cleanup will be necessary, but overall it appears to work great.
