* Created test_data folder with block json files for testing + create separate file for block base. * Fixed bug in WriteVarUint + Trim logic + unit tests * Refactored store and add more tests for it. * restore headerList from chain file * Fix tx decode bug + lots of housekeeping. * Implemented Node restore state from chain file. * Created standalone package for storage. Added couple more methods to Batch and Store interfaces. * Block persisting + tests * bumped version -> 0.31.0
