E.W.Ayers d22916fdcd feat: improve expression diff 
Added recursion cases to the diff algorithm for projections and mdata.
Previously, these would be rendered as the entire expression being different but we can do better
by checking if the recursion args are the same.

With mdata, these are entirely ignored by the diff algorithm.
