Just wondering how this works... YamlObject::get calls
YamlObject::Getter::get, and if the latter returns std::nullopt, then
the former returns the value that was passed in? (Scratching my head
ever so slightly...!)

Looking at this, I suspect we should have been checking the return
code from readYaml (equivalently, an empty Pwl from get), but that's
clearly a thing for later, and not for this patch.

Hmm, probably more return codes that weren't being checked...

So yes, that all looks good to me. Possibly worth running it on a Pi
just to double check!
