public static readonly Extension<FieldOptions, string> ColumnName
Setting the column_name extension allows users to reference
bigquery column independently of the field name in the protocol buffer
message.
The intended use of this annotation is to reference a destination column
named using characters unavailable for protobuf field names (e.g. unicode
characters).
