Add additional maintainers

There seems to be interest in this project and people are contributing PRs.
Unfortunately there is little feedback on those PRs and most issues.
metorikku looks nice and it would be a shame if it slowly degraded this way.
Would you be willing to accept additional contributors to this repo or improve collaboration with open source contributors in another way?
I'm just evaluating using metorikku for a project at work and could do some maintenance, but I'd only do this if I believe in the sustainability of this option.

Let me know what you think 😃

I'd also like to know if this project is going to be put on ice as I used it in the past and found it very useful. Please, let the community know if that is so.
