Investigate Multiple Hierarchies

[missinglink]

I noticed this record (and possibly more TBC) went from having a single hierarchy to ~35 hierarchies between the Feb 2024 & Nov 2024 releases.

Just wanted to flag it up for review since it might be valid or might indicate a bug?

Yeah, this is a bit weird, but it comes from London and the way in which it's structured: https://spelunker.whosonfirst.org/id/101750367

Given that, I think what we're doing here is correct? Agree it's a little odd though.

Plausibly we could ignore London as a thing to PIP into and pick one of the other parents, like a Borough or something else.

Agh I see, I guess that's correct? @nvkelso
