ParquetMetadataConverter offset filter is broken #1954

@asfimport

Description

@asfimport

The commit for PARQUET-384 moved block filtering by offset that was happening in the record reader into ParquetMetadataConverter using the same codepath as the existing range filter. This broke the offset filtering because the offsets actually passed to the range filter are row group midpoints.
