Review Comment:
As in the LARGE version of ByteArrayChunkedReader would still be functional
and be able to read a file generated with the below python script?
```
import pyarrow as pa
import pyarrow.parquet as pq
arr = pa.array([[("a" * 2**30, 1)]], type = pa.map_(pa.string(), pa.int32()))
arr = pa.chunked_array([arr, arr])
tab = pa.table({ "arr": arr })
pq.write_table(tab, "test.parquet")
```
