I was playing with a small parquet file which has been written with nanosecond timestamp precision by parquet-rs and when trying to convert it the Arrow schema to Iceberg, it runs into an issue with the Timestamp::Nanosecond not being recognised:

value: DataInvalid => Unsupported Arrow data type: Timestamp(Nanosecond, None)

I have a simple fix for this locally, which I'll follow up with this issue shortly for comments.
