Batch writes

[tzdybal]

Currently during Update/Delete operation every write on the path from leaf to root is done in a separate call.
Those operations could be executed as batch.
Pros:

• improved consistency (no orphaned nodes in case of crash)
• (most probably) improved performance
  Cons:
• more complicated MapStore interface

Most KV stores implements batching, and actually quite often even single operation is also wrapped in a batch (AFAIK this is true for LevelDB, RocksDB, Badger).
