vdk-oracle: support passing math.nAn and None for ingestion

[DeltaMichael]

Overview

Passing math.nAn as part of an ingestion payload currently leads to ingestion errors. Passing None has not been tested. We should support passing both without any ingestion errors.

Example:

    payload2 = {"id": 6, "float_data": math.nan, "int_data": None}
    job_input.send_object_for_ingestion(
       payload=payload2, destination_table="test_table"
    )

Acceptance criteria

1. We're able to pass math.nAn for ingestion
2. We're able to pass None for ingestion
3. There are tests covering this
