This endpoint will import a package file that was either (1) uploaded to an asset directory on the same server, or (2) on a UNC accessible to the server. The purpose of this is to work-around the extremely large file upload limit, and allow for "chunked uploading" (via an asset directory) or direct network path access.
This should default "delete the file after import"; this effectively allows for the file to be moved instead of copied. The user can specify to not delete, which would cause the file to be copied.
