I'll take a look at this tomorrow, but I think that not allowing partitioning by nested columns isn't the right solution. Iceberg can partition by columns nested in structs, but not columns inside lists or maps. Since it is just a logical grouping, I see no reason why it shouldn't be allowed. I think we just need to update the analysis check.
