Remove serialization from consensus 

Consensus now only cares about Merkleisation (i.e. `hash_tree_root`), not about serialization (i.e. `serialize`). This simplifies consensus code by a few tens of lines, is conceptually cleaner, and is more future proof.

A corresponding change is required in the deposit contract.
