Call contracts

Pull up MYKEY for contract calls, support multiple action combination calls, support ContractAction and TransferAction two types of action types. Please refer to the class definition for the parameters ContractRequest and MYKEYWalletCallback

ContractRequest contractRequest = new ContractRequest()
        // chain could be EOS, and ETH.
        .setChain(ChainCons.EOS)
        .setInfo("Perform the mortgage REX operation")
        // order ID which come from dapp server
        .setOrderId("BH1000001")
        // DApp CallbackUrl
        // param：{"protocol": "", "version": "", "tx_id": "", "ref": "", "account": ""}
        // return: same as SimpleWallet {"code": [0-2], "message": ""}
        .setCallBackUrl(Config.DAPP_CALLBACK_URL);
ContractAction contractActionRequest = new ContractAction();
contractActionRequest.setAccount("eosio")
        .setName("buyram")
        .setInfo("buy ram")
        // JSON string support, eg:setData("{\"player\":\"bobbobbobbob\",\"receiver\":\"alicealice11\",\"quant\":\"1.0000 EOS\"}")
        .setData(new BuyRamDataEntity().setPayer("bobbobbobbob").setReceiver("alicealice11").setQuant("1.0000 EOS"));
contractRequest.addAction(contractActionRequest);


/**
For the call contracts of ETH, please pay attention to below items:
a. Before sending data to MYKEY, determine if it is a contract action, the chain is ETH, and the binary is empty, then call the Go method ethJsonToBinary to generate a binary
b. Before sending data to MYKEY, make sure that all actions have the chain field set (the original chain field should be on the outermost Contract object)
c. ETH SDK does not support multi-action
