unpack takes an uint64 and returns two uint32 (as uint64) comprised of the leftmost and the rightmost bits respectively.

// unpack takes an uint64 and returns two uint32 (as uint64) comprised of the leftmost
// and the rightmost bits respectively.
func unpack(in uint64) (uint64, uint64) {
	return in >> 32, in & 0xffffffff
}

// pack takes two uint32 (as uint64 to avoid casting) and packs them into a single uint64
// at the leftmost and the rightmost bits respectively.
