Description

we should add support for protobuf OneOf fields to Spark-Protobuf. This will involve implementing logic to detect when a protobuf message contains a OneOf field, and to handle it appropriately when using from_protobuf and to_protobuf. 

we should add unit tests to ensure that the implementation of protobuf OneOf field support is correct.

Users can use protobuf OneOf fields with Spark-protobuf, making it more complete and useful for processing protobuf data.
