### What changes were proposed in this pull request?
Add RowToColumnConverter for BinaryType
### Why are the changes needed?
currently, we have RowToColumnConverter for all data types except BinaryType
```
private def getConverterForType(dataType: DataType, nullable: Boolean):
TypeConverter = {
val core = dataType match {
case BooleanType => BooleanConverter
case ByteType => ByteConverter
case ShortType => ShortConverter
case IntegerType | DateType => IntConverter
case FloatType => FloatConverter
case LongType | TimestampType => LongConverter
case DoubleType => DoubleConverter
case StringType => StringConverter
case CalendarIntervalType => CalendarConverter
case at: ArrayType =>
ArrayConverter(getConverterForType(at.elementType, at.containsNull))
case st: StructType => new StructConverter(st.fields.map(
(f) => getConverterForType(f.dataType, f.nullable)))
case dt: DecimalType => new DecimalConverter(dt)
case mt: MapType => MapConverter(getConverterForType(mt.keyType,
nullable = false),
getConverterForType(mt.valueType, mt.valueContainsNull))
case unknown => throw
QueryExecutionErrors.unsupportedDataTypeError(unknown.toString)
}
```
so add one for BinaryType
