kind + hash + index + height + value:
[0] + [40]:[1 + 15] + [0] + [56] = 112
8 + 256:16 + 32 + 64 = 376
112/376 = 30% of original table size (22.5GiB).

Initial re-implementation (reversed point):
[8] + [16]:[64] + [0] + [64] => 148 / 376 => 39% (40.5GiB)
The remaining optimizations are internal to the serializer with the exception of converting to 40 bit tx slab addressing, which is a distinct issue.
