Tobey now has Windows builds
Thanks to the help of Abdullah, who figured out why my initial tries at a Windows build failed, Tobey now has Windows builds. It never even crossed my mind that by using the latest C++ standard, there may be compilers that don't support it yet, which was the case here with MinGW. I've now switched to using MSVC.
I intend to make the installation process easier soon as well, so that Windows users could install Tobey with something like scoop or chocolatey, and Linux users with perhaps an installation script or a package manager as well.
