We first define helper functions:
* `pack`: Given ordered objects of the same basic type, serialize them, pack them into 32-byte chunks, right-pad the last chunk with zero bytes, and return the chunks.
* `merkleize`: Given ordered 32-byte chunks, right-pad them with zero chunks to the closest power of two, Merkleize the chunks, and return the root.
* `merkleize`: Given ordered 32-byte chunks, right-pad them with zero chunks to the next power of two, Merkleize the chunks, and return the root.
* `mix_in_length`: Given a Merkle root `root` and a length `length` (32-byte little-endian serialization) return `hash(root + length)`.
Let `object` be an object. We now define object Merkleization `hash_tree_root(object)` recursively:
