This doesn't have a fast-path to avoid
BCryptGenRandomif it is known to fail.Thus this is probably gonna get expensive for some users, I can add some fast-path though.
Right now I don't have a Windows machine to actually test it on (but CI should do that, I also have acess to a machine again next week).
I'm not 100% sure yet that it fixes the crashes we see on Firefox, but given the stdlib switched to a similar solution I have hopes.
