Support criterion badges for projects

[axolotl-logic]

Hello!

I want to show off my Criterion pride in the tech stack section of my Github profile and I'm stuck on your library and a few others.

A lot of GitHub users use shield.io (unaffiliated) for this. I did some research and they pull their logos from Simple Icons.

My research stopped there, but I bet if you were to find a way to submit your logo to that SVG repository, everyone could do it

Edit:

For full disclosure, once this ticket concludes and I've figured out the exact process, I'll probably send a similar spiel to other repos -- but you're the first.

I really like there being an alternative to GTest and I saw you give a talk a few years back.
