Investigave need for a DynamoDBQuery failure state

[nhyne]

There may be a need for an error channel in the DynamoDBQuery trait. In cases where users can pass invalid options it may be beneficial to provide them with an error and let them account for those cases. After a short discussion with John he suggested that it could be modeled after ZIO's die/dieMessage/failCause.

We would also be able to write helpers like DynamoDBQuery.when(f: A => Boolean) that would produce a failed DynamoDBQuery in the event that the passed function returned false.
