Compare parquet-mr version with SemanticVersion in ValidInt96Stats

String.compareTo is lexicographic: "1.15.1".compareTo("1.16.0") returns -1,
which incorrectly rejected parquet-mr 1.15.1 (caught by testParquetMrValid)
and also accepted hypothetical pre-1.15 versions like 1.5.0 (since '5' > '1'
at position 2). Use SemanticVersion compareTo with a 1.15.0 lower bound;
strict > so 1.15.0 itself stays invalid, matching testParquetMrInvalid.
