ParquetWriter invokes Stream.Write with empty buffer for empty values

[yifatsor]

From version 3.5.3 (or maybe prior to it), when writing empty values, Stream.Write(byte[] buffer, int offset, int count) is invoked with buffer=byte[0], offset=0, count=0. Some streams implementations throw an exception in this case. This did not happen with earlier versions (I know it didn't happen with 3.3.4, I don't know when in between this was introduced). Would be great if you can fix it to not invoke the stream.Write method when there's nothing to write. repro: invoke ParquetWrite with some empty values.

Version: Parquet.Net v...

Runtime Version: .Net Framework v, .Net Core v etc.

OS: Windows/Linux/MacOSX v etc.
