Proposal: Release the Windows builds in another repo

[kleisauke]

Because we might be able to deliver a lot of extra files (see #4) it might be useful to release them in a separate repo. We could rename this repository to windows-builds (this repo is no longer dedicated to 64-bit, it also supports 32-bit Windows) and release the files here.

A build chooser can also be very handy, see for example the Windows build chooser of FFmpeg: https://ffmpeg.zeranoe.com/builds/

We can do something similar for this repo and host it on GitHub Pages.
