I saw issues with GenericOrcWriter w.r.t. date/time/timestamp/decimal types when I tried to extend `org.apache.iceberg.data.DataTest` for ORC.
e.g.
For date type
```
java.lang.IllegalStateException: Not an instance of java.lang.Integer: 1619-02-13
at org.apache.iceberg.data.GenericRecord.get(GenericRecord.java:123)
at org.apache.iceberg.data.orc.GenericOrcWriter$StructConverter.addValue(GenericOrcWriter.java:336)
at org.apache.iceberg.data.orc.GenericOrcWriter$StructConverter.addValue(GenericOrcWriter.java:312)
```
For timestamp type,
```
java.lang.IllegalStateException: Not an instance of java.lang.Long: 1978-08-10T16:28:30.954017Z
at org.apache.iceberg.data.GenericRecord.get(GenericRecord.java:123)
at org.apache.iceberg.data.orc.GenericOrcWriter$StructConverter.addValue(GenericOrcWriter.java:336)
at org.apache.iceberg.data.orc.GenericOrcWriter$StructConverter.addValue(GenericOrcWriter.java:312)
```
For decimal type,
```
java.lang.ArithmeticException: Rounding necessary

at java.math.BigDecimal.needIncrement(BigDecimal.java:4204)

at java.math.BigDecimal.longValueExact(BigDecimal.java:3090)

at org.apache.iceberg.data.orc.GenericOrcWriter$Decimal18Converter.addValue(GenericOrcWriter.java:259)
at org.apache.iceberg.data.orc.GenericOrcWriter$StructConverter.addValue(GenericOrcWriter.java:336)
```
We can probably address this in a future PR though?
