Use ZIP for Windows builds rather than TAR.GZ

[unfa]

Hey! First off - thank you so much for picking up BeeRef. It's an excellent tool and there isn't anything like it that it's a proprietary black box.

I think it'd be nice to compress the Windows builds of BeeRef into a zip archive, as it's natively supported by the system, unlike tarballs. Extracting a tar.gz file on Windows requires extra software (I use 7zip anyway, but fro some people it might be a hassle).

Thanks!
