BigQueryAvroUtils.java contains useful methods, can we change its visibility to public ?

Reading from BigQuery using the Avro GenericRecord API is fast but low-level and error prone due to the particularities of Type mappings between BigQuery and Avro types.

The class BigQueryAvroUtils contains useful methods that are helping clients to solve mapping issues, converting from TableRows to Generic records etc.. (ex: https://stackoverflow.com/questions/51459902/avro-genericrecords-bigquery-and-beam ).

Would be possible to change visibility of this class in order to be able to use directly these methods.

Thanks,
