Describe the bug
File size is not populated in the DB for Frames.

To Reproduce
Steps to reproduce the behavior:
Run query:

query GetFrameFileSizesSimple($datasetId: Int!) {
  datasets(where: { id: { _eq: $datasetId } }) {
    runs {
      edges {
        node {
          frames {
            edges {
              node {
                fileSize
              }
            }
          }
        }
      }
    }
  }
}

with

{
  "datasetId": 10448
}

returns

{
  "data": {
    "datasets": [
      {
        "runs": {
          "edges": [
            {
              "node": {
                "frames": {
                  "edges": [
                    {
                      "node": {
                        "fileSize": 0
                      }
                    },
                    {
                      "node": {
                        "fileSize": 0
                      }
                    },
                    {
                      "node": {
                        "fileSize": 0
                      }
                    },
                    {
                      "node": {
                        "fileSize": 0
                      }
                    },
.....

Expected return value: the file size.
