* rebased from `github/on-demand-mpt` ackn: wip: on-demand mpt construction Given that actual data is stored in the `Vertex` structure, it's useful to think of the MPT as a cache for computing roots rather than being a functional requirement on its own. This PR engenders this line of thinking by incrementally computing the MPT only when it's needed, ie when a state (or similar) root is needed. This has the effect of siginficantly reducing memory usage as well as improving performance: * no need for dirty-mpt-node book-keeping * no need to build complex forest of upcoming hashing work * only hashes that are functionally needed are ever computed - intermediate nodes whose MTP root is not observed are never computed / processed * Unit test hot fixes * Unit test hot fixes cont.
