make compatible with windows#142

so the app can be used on computers

While we of course understand that a Windows app would make Wokabulary accessible to even more users, we have to say that we are not planning to implement versions for other platforms in the nearer future. We are a small team of iOS and Mac developers and focus on these platforms. In fact we plan to integrate even deeper with platform specific features on iOS, iPadOS and macOS (like widgets).

Closing this as a duplicate of #42
