Native Windows Support

Hi, thanks for the great software.

Since there's already an issue here, but quite old:
https://github.com/GothenburgBitFactory/taskwarrior/issues/1245

I'd like to ask again if it is possible to provide native windows support.
I've seen plugins that build on top of this software, like `tasklib`, `taskwiki` etc, but since **TaskWarrior** only support linux environment, there's no way to use these outside the WSL environment for Windows users.

The growing number of cmd tools for windows users as well as package management system like `scoop` and `choco` are making native Windows development more and more popular.

native Windows support will be really a nice thing to have. Please support!
