fix: ScriptedContracts in Origination

Origination operation has a "script" field. Tezos description says:
[https://tezos.gitlab.io/shell/p2p_api.html#origination-tag-109]
 - size: determined from data
 - contents: $alpha.scripted.contracts
The ScriptedContracts type is matching the definition of
$alpha.scripted.contracts
[https://tezos.gitlab.io/shell/p2p_api.html#alpha-scripted-contracts]
 - # bytes in next field, 4 bytes, unsigned 30-bit big-endian integer
 - code, Variable, bytes
 - # bytes in next field, 4 bytes, unsigned 30-bit big-endian integer
 - storage, Variable, bytes

 Fixed the definition of TezosOriginationOperation to match the TezosRPC
 specification.
