  1. Initial SMT store type 

    SMT (Sparse Merkle Tree) is intended to replace IAVL. New type
implements same interfaces as iavl.Store.

  2. Add iteration support to SMT 

    Sparse Merkle Tree does not support iteration over keys in order.
To provide drop-in replacement for IAVL, Iterator and ReverseIterator
has to be implemented.
SMT Store implementation use the underlying KV store to:
 - maintain a list of keys (under a prefix)
 - iterate over a keys
Values are stored only in SMT.

  4. Store data in ADR-040-compatible way 

    SMT stores:
 * key -> hash(key, value)

KV store stores:
 * key->value in "bucket 1",
 * hash(key, value) -> key in "bucket 2".
