x/perf/cmd/benchstat: GitHub markdown table output

[mdempsky]

GitHub supports tables in markdown format: https://help.github.com/en/articles/organizing-information-with-tables

It would be handy if benchstat could easily output in this format for pasting benchstat output into issues.

Is this issue taken? If not, I would like to work on this.

@ashley Okay by me, but I'm not in charge of benchstat.

Two caveats I realized after filing the feature request:

1. GitHub doesn't handle wide tables very well, but maybe this was just because I had very long test names with a lot of measurements. At least worth playing around with.

2. benchstat does have CSV output, so maybe a csv2markdown tool would be more generally useful (and maybe already exists)? I can see arguments either way.

@mdempsky There's actually a work around for this. Benchstat has a -html flag, and you can use the <table>...</table> component in GitHub or any Markdown file. That being said, maybe @dmitris can help decide whether it is worth adding a markdown flag to benchstat.

[mdempsky]

Oh, I didn't know GitHub supported HTML tables too. Good to know.

It looks like the recent version of benchstat golang/perf@02c5517 does not support HTML output anymore. Are there any plans to add this back?
