Non-conforming Isaac64 PRNG

[nebulaeonline]

I know this is an older project, but people are probably always looking for a fast PRNG.

Your implementation does not seem to output numbers that jive with those generated from the original C implementation by Bob Jenkins: https://[burtleburtle.net/bob/c/isaac64.c](https://burtleburtle.net/bob/c/isaac64.c

It also does not match the expected output published by the Rust project here: https://docs.rs/rand_isaac/latest/src/rand_isaac/isaac64.rs.html#84

Nor does it match the expected output published by Zig here: https://github.com/ziglang/zig/blob/master/lib/std/rand/Isaac64.zig

I'm an Isaac fan, and your work is great.

The code in your repo outputs the following as the first 16 random 64-bit integers on an unseeded run:

Rng #0 == 0x9d39247e33776d41
Rng #1 == 0x2af7398005aaa5c7
Rng #2 == 0x44db015024623547
