The opensearch_api source did not work with Kafka buffer because no ByteDecoder was registered. When buffer.isByteBuffer()=true, raw bytes are written but the consumer side had no way to reconstruct events from the NDJSON bulk format. This adds OpenSearchBulkByteDecoder which parses NDJSON bulk format (action/metadata + document line pairs) back into Data Prepper events with correct metadata attributes.
