Review Comment:
ParquetFileReader truly reads all children fields of `s` in
readNextRowGroup(). But the parquet vectorized reader only reads `p1, s_f4,
s_f2.q1, s_f3` from ParquetFileReader.
However, The requestedSchema here should only contains necessary columns.
`f1` should be exclude here. Then ParquetFileReader only reads the pages
contain `s_f4, s_f2.q1, s_f3`. I will fix this later.
