Formats skpbench.py outputs as csv.

This script can also be used to generate a Google sheet:

(1) Install the "Office Editing for Docs, Sheets & Slides" Chrome extension:
    https://chrome.google.com/webstore/detail/office-editing-for-docs-s/gbkeegbaiigmenfmjfclcdgdpimamgkj

(2) Update your global OS file associations to use Chrome for .csv files.

(3) Run parseskpbench.py with the --open flag.
