Should be able to get there reusing other bits
For multiple-structs, `pivot` has something that can work IIRC

enhancement
The benefit of `Series.struct.unnest` is to get the field names *"for free"* ...but we already have them - so `ChunkedArray.flatten` is good enough
I've already checked and found the columns to be duplicated Just reusing that path to display the duplicate(s) consistently
- Using `DType.__eq__` is a waste of time - No idea why I aliased `dtypes` there

Description
Back from a little detour w/ #3396 to finally conclude the missing features for
LogicalPlanseries (start from #3364).This one is
DslFunction::Unnest, which we currrently don't have an equivalent of onmain.It'll come up eventually 😅
