Description

As of now, test tables are generated with Spark + Hudi, and we should also be testing on tables that are created with Flink.

Flink supports Timestamp with different precision, HudiAvroSerializer definitely does not support these now.

Add tests to cover such blindspots for now.

Research direction

Start with the existing smoke tests for tables generated with Spark + Hudi and inspect HudiAvroSerializer handling of timestamp precision. Add coverage for tables written by Flink, including its different timestamp precisions, and verify the tests expose the currently unsupported cases.
