Research direction
Start at the convertINT96 method shown in the issue and inspect the surrounding Parquet-to-Arrow type mapping. Confirm the appropriate FixedSizeBinary representation for int96 when convertInt96ToArrowTimestamp is false, then verify the resulting mapping with the relevant conversion tests.

Description
Describe the enhancement requested
public TypeMapping convertINT96(PrimitiveTypeName primitiveTypeName) throws RuntimeException {
if (convertInt96ToArrowTimestamp) {
return field(new ArrowType.Timestamp(TimeUnit.NANOSECOND, null));
} else {
return field(new ArrowType.Binary());
}
}
When converting a Parquet type to an Arrow type, if the original type is int96 and the option convertInt96ToArrowTimestamp is set to false, the resulting Arrow type defaults to Binary. However, it might be more appropriate to use FixedSizeBinary instead.
