Urand compile fails on Windows about npg

[rustomax]

Did a major rework of nim-passgen library that NPG is based on to use nimcrypto random number generator. This enabled a much wider platform support, including Windows, Linux, MacOS and some versions of BSD.

It seems that the issue is caused by CryptGenRandom being deprecated: https://docs.microsoft.com/en-us/windows/desktop/api/wincrypt/nf-wincrypt-cryptgenrandom. It must be missing in my Windows 10 Insider build.
nim-random uses it for urandom on Windows: https://github.com/oprypin/nim-random#randomurandom
Why can't we switch to the random module from stdlib?

Now you can try std/sysrand, though it is on devel and expermental.

@xflywind correct, I didn't want use random from stdlib because of known quality issues. See for instance, https://forum.nim-lang.org/t/6843#42756. I'll look into what's available when I get the chance. Thanks for the pointer to std/sysrand.
