Fix tow bugs:
1. Unexpected null values in array column. If 65535 consecutive values are not null in nullable array column, this error will be triggered. The reason is that the array parser did not handle boundary conditions.
2. The number of rows of key filed, and that of value field in map column are not equal. Similarly, the number of rows among fields in struct column are not the same. This would be triggered when the number of rows are not equal among parquet pages of different columns in a row group.
