Thank you for this contribution.  The paper is well cited, so this is a good candidate for inclusion.

I had a brief look at the PR: the implementation is fairly straightforward and needs mostly stylistic alterations.  I'm glad to see you've already received some feedback from Pamphile.

Best regards,
Stéfan
