[dataflow-data-generator] TypeError: '>' not supported between instances of 'str' and 'int' [while running 'Generate Data']

Looks like there is an issue in the code that is comparing a string with an int:

record[fieldname] > max_size:

Looks like record[fieldname] holds a str instead of an int

**Running this command:**
python3 data-generator-pipeline/data_generator_pipeline.py \
--project=bank-bigquery --setup_file=data-generator-pipeline/setup.py \
--worker_machine_type=n1-highcpu-32 --runner=DataflowRunner \
--staging_location=gs://bank-raw-data/test --temp_location=gs://bank-raw-data/temp \
--schema_file=gs://bank-raw-data/schemas/DMR1999_AU_CONTRATOS.json --output_bq_table=datamart.DMR1999_AU_CONTRATOS \
--p_null=0.05 \
--num_records=10000 --save_main_session

**I got this error:**
