Create a contract and exercise a choice on it in the same transaction.

    commandType: 'create',
    templateId: {
        packageId: 'some-package-id',
        moduleName: 'SomeModule',
        entityName: 'SomeTemplate'
    },
    createArguments: {
        fields: {
            owner: {
                valueType: 'party',
                party: 'Alice'
            }
        }
    },
    choice: 'Issue',
    choiceArgument: {
        valueType: 'record',
        fields: {
            quantity: {
                valueType: 'int64',
                int64: '100'
            },
            price: {
                valueType: 'decimal',
                decimal: '42'
            }
        }
    }
