Using large memory block, read or write is getting corrupted

[object88]

Example code; causes an issue with hashmaps with large data sets.

Width is set to 53, because large hashmaps contain significant low-order bytes, and we are attempting to use 64-bit hashes.

src := rand.NewSource(time.Now().UnixNano())
random := rand.New(src)

width := uint32(64 - 11)
max := int64(math.Pow(2.0, float64(width)))

count := uint64(8)
contents := make([]uint64, count)
for i := uint64(0); i < count; i++ {
	contents[i] = uint64(random.Int63n(max))
}

m := AllocateMemories(LargeBlock, width, 8)
for k, v := range contents {
	m.Assign(uint64(k), v)
}

for k, v := range contents {
	result := m.Read(uint64(k))
	if result != v {
		t.Fatalf("At %d\nexpected %064b\nreceived %064b\n", k, v, result)
	}
}

Fixed in #36 .
