Go benchmark results include an Average, represented as
<mean> ± <standard deviation>
This is suboptimal for many reasons:
* Some web server somewhere in our CI pipeline (Cirrus?
Google? Gitlab? I have no idea) sends the wrong mime-type
header, rendering the CSV weird-looking in a browser.
Not that it's intended for a browser, but we have to
debug/verify manually once in a while.
* The spaces and +/- makes it less machine-readable.
Solution: split the "Average" field into two: Average, and
Standard Deviation. And, as a courtesy to human readers,
add a new column with SD as a percentage.

New script for use with Valentin's benchmarks. Converts ginkgo
timing results to CSV format suitable for (TBI) saving and
comparing.
