Oxford Reading Tree - Title cleanup, series -> editionfield

[☕ Lachgas ♿]

That series needs a "bit" of title cleanup (was Treetops Oxford Reading before but as Oxford Reading doesn't make the series I removed that)

The title needs to be cleaned on the books and the Oxford Reading Tree goes to the edition field.
The stages go into description as far as I know.

I can't take that one because I'm still on another of these Oxford Reading Tree "series"

Shouldn't these be made into a Listopia instead of a series?

I assumed that Tree Tops thing is a character . my fault for not checking .. yes looks more like not a series

So it's then Oxford Reading Tree: Tree Tops?
or Oxford Reading: Tree Tops?
