* 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
