> ParquetIO is missing output coder when using a user-specified parsing
> function with `parseGenericRecord` or `parseFilesGenericRecord` feature for
> reading Parquet files with unknown schema.
> *Workaround:*
> Use `setCoder` directly on the output `PCollection`
> for example:
> {{SerializableFunction<GenericRecord, Foo> parseFn = ...;}}
> {{Coder<Foo> fooCoder = ...;}}
> {{PCollection<Foo> records =
> }}{{p}}{{.apply(ParquetIO.parseGenericRecords(parseFn).from(...))}}
> {{*.setCoder(fooCoder)*;}}
