Build fails on Windows because of termion

[poopsicles]

The build fails on Windows as the termion library isn't supported on Windows

Perhaps Windows support should then be removed from the README, or an alternative would be to use a cross-platform terminal library, such as crossterm

[Samyak2]

I realized after updating the README and publishing the release that termion does not support windows.

I had made the decision to use termion when starting this project despite it not supporting Windows. I don't have any plans to switch to crossterm yet - I'll consider it after some of the other bugs and features are done.

For the moment, I'll add a note in the README mentioning that Windows is not supported.

There's always WSL though :p
