ncurses support on windows

[karlstav]

          Hey @karlstav! I was able to build cava from source on Windows and both `sdl` and `sdl_glsl` outputs are working 💖

However since cava is popularly used in terminals, how can I use the ncurses or notcurses output?

(ncurses is available in the MSYS2 environment, see https://packages.msys2.org/base/mingw-w64-ncurses. Notcurses, while not readily available, can also be built inside the MSYS2 environment, see https://github.com/dankamongmen/notcurses/blob/master/INSTALL.md#microsoft-windows)

we already have noncurses support on windows. it should support all the features that ncurses does, but the performance is poor. @rashil2000 have gotten it working on msvc with the ncurses lib from mingw and reports that performance is better, but redefining colors is not working.
