f3abbf34e3 mpt: fill cached fields when getting node from store

df1792c80b mpt: export func for decoding node with type

f77c239296 mpt: fix extension node cache invalidation
It should always be invalidated if something changes in the `next` (below the
extension node).

103c45850a mpt: implement (*Trie).Collapse()
Because trie size is rather big, it can't be stored in memory.
Thus some form of caching should also be implemented. To avoid
marshaling/unmarshaling of items which are close to root and are used
very frequenly we can save them across the persists.
This commit implements pruning items at the specified depth,
replacing them by hash nodes.

9c478378e1 mpt: implement JSON marshaling/unmarshaling
Because there is no distinct type field in JSONized nodes, distinction
is made via payload itself, thus all unmarshaling is done via
NodeObject.

861a1638e8 mpt: implement MPT trie
MPT is a trie with a branching factor = 16, i.e. it consists of sequences in
16-element alphabet.
