   ### Describe the bug
   
   Fixed in https://github.com/apache/datafusion/pull/19123
   
   Currently if you have an expression on the left and the right that results 
in the same name, you get an error when converting from substrait. This is due 
to the fact that substrait only references columns by their position rather 
than their attribute name so during conversion expressions are named as their 
default i.e `CAST(...)` rather than keeping their original name.
   
   The fix implemented is to alias all projected expressions with a UUID, this 
makes the plan less readable but does make it correct. Because there is a 
decision to be made here about the readability of the plan I've made it a 
config on the session such that the user can decide which mode it should 
operate in.
