support expected non-cube exportable tables

[James-R-Jones]

Not in scope that these tables get aggregated across multiple sites in the traditional sense so I get it, but guys like these should probably not be told to go sit in the corner when they show up as expected:

https://github.com/smart-on-fhir/cumulus-library-data-metrics/tree/main/cumulus_library_data_metrics/c_resources_per_pt
https://github.com/smart-on-fhir/cumulus-library-data-metrics/tree/main/cumulus_library_data_metrics/q_date_recent
https://github.com/smart-on-fhir/cumulus-library-data-metrics/tree/main/cumulus_library_data_metrics/q_ref_target_pop
https://github.com/smart-on-fhir/cumulus-library-data-metrics/tree/main/cumulus_library_data_metrics/q_ref_target_valid
https://github.com/smart-on-fhir/cumulus-library-data-metrics/tree/main/cumulus_library_data_metrics/q_system_use
https://github.com/smart-on-fhir/cumulus-library-data-metrics/tree/main/cumulus_library_data_metrics/q_valid_us_core_v4

expected behavior: returned exported tables where aggregation is not required still show up in last_valid for retrieval and management
current behavior: flagged as errors
