`FileReaderImpl::ReadRowGroup` fails with "Nested data conversions not implemented for chunked array outputs". It fails on [ChunksToSingle](<https://github.com/apache/arrow/blob/7f6b074b84b1ca519b7c5fc7da318e8d47d44278/cpp/src/parquet/arrow/reader.cc#L95>) Data schema is: ```java optional group fields_map (MAP) = 217 { repeated group key_value { required binary key (STRING) = 218; optional binary value (STRING) = 219; } } fields_map.key_value.value-> Size In Bytes: 13243589 Size In Ratio: 0.20541047 fields_map.key_value.key-> Size In Bytes: 3008860 Size In Ratio: 0.046667963 ``` Is there a way to work around this issue in the cpp lib? In any case, I am willing to implement this, but I need some guidance. I am very new to parquet (as in started reading about it yesterday).
