* deleted transfer_output added asset type and transaction result to core

* removed writing 0x00 when buffer length is 0

* Refactored emit into VM package + moved tx to own package.

* implemented transaction along with claimTransaction.

* refactored naming of transaction + added decode address for uint160 types

* removed unnecessary folder and files.

* transaction/smartcontract logic

* bumped version 0.24.0
