Evgeniy Kulikov 6ccb518ab0 Optimizations + some improvements (#105)
* Optimizations + some improvements

- optimized pkg/core/storage.HeaderHashes
- optimized pkg/rpc.performRequest (used json.Encoder)
- fixes for pkg/util.ReadVarUint and pkg/util.WriteVarUint
- optimized and fix fixed8 (Fixed8DecodeString / MarshalJSON) + tests
- optimized and fix uint160 (Bytes / Uint160DecodeString / Equal / MarshalJSON) + tests
- optimized and fix uint256 (Bytes / Equal / MarshalJSON) + tests
- preallocate for pkg/vm.buildStackOutput
- add go.mod / go.sum

* update version
