Add desktop versions For Win/MacOS/Linux with Electron/Tauri

[tomchen]

The web app works fine in modern browsers. But add desktop versions just for the sake of completeness.

The game runs very well in Google Chrome (and browsers with Chrome's engine), a bit slow in Firefox & Safari (depends on the machine though), and doesn't work in legacy browsers. An Electron app can help non Chrome users.

See electron branch

• [x] Windows
• [ ] MacOS
• [ ] Linux

Edit: May consider Tauri instead of Electron

From a product development perspective, I'd hold off on broader compatibility this until the release lifecycle slows down. Unless you have a totally automated release process, it is burdensome to have to push little updates to different platforms.

I am primarily a linux user myself, but I could see supporting different flavors of linux being a challenge. Flatpak/flathub could help with that.
