Subject: [PATCH] Add support for Windows

Ported termkey for windows.

- The TERMKEY_FLAG_NOTERMIOS is ignore in Windows, since there is no termios.
- The termkey_waitkey() function is not implemented in windows, since there
  is no poll() alternative.
- The CMake recipe only supports unibilium, not curses.
