This is fine. But Ideally, we want this to be a sum type instead of a product type? But then we get whole loads of matches everywhere?

The main reason to use a product type was that Taproot descriptors have both single keys and (optionally) a taptree iterator.
And in PkIter::next I have a construction where the taptree iterator yields new Miniscript pkiters.
I can try to refactor this to use a sum type but I think it would result in more repeated/redundant code.

Yeah, that would be messy. Ideally, we want to stick the mantra of "make invalid states unrepresentable"; but it might be overkill for this small change

Fixes #821.
Should backport to 12.x.
