Add Krippendorff’s alpha?

[ericphanson]

It is a measure of inter-rater reliability and there is a Julia package to compute it: https://discourse.julialang.org/t/ann-krippendorff-jl/54261

I'd be interested to hear @mbwestover's opinion here.

We discussed this during our sync meeting today; the consensus was it would be great to have as an additional interrater-reliability measure but wasn't a priority for us to implement in Lighthouse.

@FPGro if you or anyone else were up for adding it to Lighthouse, we'd be glad to get a PR!

Sounds reasonable. I'll come back to this as soon as I have enough tests in place to feel confident registering the package.
