DRILL-5797: Choose parquet reader from read columns
ParquetRecordReader is not able to read complex columns. However it is
able to read simple columns in a file containing complex
columns. Instead of looking at the file to choose the reader, we
now choose which reader to use based on what columns is asked and if
they are simple or not.
