We might as well precompute the node digits here ...

```
if (useCrypto) {
crypto.getRandomValues(rnds);
} else {
rnds[0] = Math.random() * 0x100000000;
rnds[1] = Math.random() * 0x100000000;
}

var node = [
rnds[0] & ff | 0x01, // Set multicast bit, see 4.1.6 and 4.5
rnds[0]>>>8 & ff,
rnds[0]>>>16 & ff,
rnds[0]>>>24 & ff,
rnds[1] & ff,
rnds[1]>>>8 & ff
]
```
