Hi,

We allow customising the {{batch_size}} when streaming to BigQuery but the 
batch duration (used by {{GroupIntoBatches}}) is set to 
{{DEFAULT_BATCH_BUFFERING_DURATION_LIMIT_SEC}} (0.2)

I'd like to add the option to specify the {{batch_duration}} to allow better 
batching for scenarios with little data throughput.
