Attribute of transaction_id

import dataflow as df
graph = df.FlowGraph(...)
flowinfo = FlowInfo(...)
flowinfo.transaction_id = 10

This function takes effect only when set_contains_n_mapping_node is set to true.
The value of transaction_id can be only increased. If not set externally, the value of transaction_id starts from 1 in auto-incremented mode.
An error is reported when the value of transaction_id reaches the value of uint64_max.
If data alignment is enabled, ensure that the value of transaction_id in each batch of input data is the same. Otherwise, data may be not aligned.
The value of transaction_id can be defined by users only when it is not set to 0.
