Suggestion: Add more collaborators

[eXpl0it3r]

When I opened a PR in 2020, it took like two months to get merged. There's a new PR #5 sitting for a few days now.

Maybe it would make sense to have more people added as collaborators to maintain the repo, so it's not just depending on @JustCaptcha?

I've seen great success in https://github.com/fffaraz/awesome-cpp where the author has added a lot of people.

Just a suggestion 🙂
