$import Response Definition

[anthonygalba]

The UDS+ IG does not fully define what the $import operation response will look like.
There is an example of the headers here: https://fhir.org/guides/hrsa/uds-plus/requestresponseexamples.html, but there is no example of the actual response.
Based on testing in the sandbox, it appears that we get back an array of "issues" that contain OperationOutcomes

Our FHIR parser throws this out as invalid FHIR, as we'd typically expect either a single OperationOutcome resource or Bundle containing more OperationOutcomes.
Similar to the request in Issue #59 would it be possible to get the $import response to use either one of those options?
