Parses output files from skpbench.py into 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.
