NASCAR API - Timestamps for Flag Events

We've added timestamps for flag events in our NASCAR API. A created_at dateTime value will be present going forward for all race flag states. See below for sample data.

⭐ Benefit

Use the timestamps to get an accurate ordering of all NASCAR race flag events.
