add support for windows

[prabirshrestha]

Would it be possible to support windows via PDCurses?

pancurses is a rust carte which uses ncurses in linux/mac and fallbacks to pdcurses on windows.

Might have to first implement multiple backend support like how Cursive does so it can work without ncurses if users prefer it.

Yes please add Windows support!
At least for the library part of rff (which doesn't need pancurses).
I want to use rff as a library for text processing in a research project..
