Compatibility with Ruby 2.7 on Windows

[Isty001]

I tried to install Curses while using Ruby 2.7 on Windows, but it seems 2.7 is not allowed yet.

      curses (~> 1.3.2) x64-mingw32 was resolved to 1.3.2, which depends on
        Ruby (< 2.7.dev, >= 2.5) x64-mingw32

Could you please take a look at it if it's possible to change the requirement?

I'm trying to disable fat binaries to support newer versions of Ruby in the following branch:

https://github.com/ruby/curses/tree/disable_fat_binaries

However, ncurses is used instead of bundled PDCurses, and I'm invesitigating.

@Isty001 I've released curses-1.4.0. Please try it.

You need DevKit to install curses.
Bundled PDCurses is used by default, but you can use ncurses with --use-system-libraries.

Seems to be working, thank you!
