Report job status in a Google Sheet ...

There is a [summary widget](https://github.com/GoogleCloudPlatform/testgrid#summary-widget) that allows the generation of SVG to report on the status of a job for inclusion in places where HTML can be rendered. Very nice.

I have a use case where I would like to report on the status of a job in a Google Sheet. I cannot find a way for it to consume the SVG returned by test-grid.

It would be great if the tests_status could be paramerized to return full XML so that it can be processed by the [IMPORTXML](https://support.google.com/docs/answer/3093342?hl=en) function on Sheets, ( I tried passing in the SVG as XML but AFAIC tell Sheets refused to treat the SVG as XML)
